Localization - I18N/L10N Usage and SetupRewritten by Michael Chin-Yuan Wu
keichii@mail.utexas.edu, 6 March 2000.SynopsisThis section of the handbook discusses the internationalization
and localization of FreeBSD to different countries and different
settings. If the users wish to use languages other than the system
default English, he/she will have to setup the system accordingly.
Please note that language support for each language varies in level.
Hence, the user should contact the respective FreeBSD local group
that is responsible for each language.The author realizes that he may have been incomplete in the
description of the i18n process in FreeBSD. Due to the various
levels of i18n implementation in both the system and applicational
levels, we advise you to refer to individual documentation, man
pages, READMEs, and so forth.Should you have any questions or suggestions regarding this
chapter, please email the author.The BasicsWhat is i18n/l10n?Developers shortened internationalization into the term i18n,
counting the number of letters between the first and the last
letters of internationalization. l10n uses the same naming
- scheme, coming from “localization”. Combined
+ scheme, coming from "localization". Combined
together, i18n/l10n methods, protocols, and applications allow
users to use languages of their choice.I18n applications are programmed using i18n kits under
libraries. It allows for developers to write a simple file and
translate displayed menus and texts to each language. We strongly
encourage programmers to follow this convention.Why should I use i18n/l10n?I18n/l10n is used whenever you wish to either view, input, or
process data in non-English languages.What languages are supported in the i18n effort?I18n and l10n are not FreeBSD specific. Currently, one can
choose from most of the major languages of the World, including
but not limited to: Chinese, German, Japanese, French, Russian,
and others.Using LocalizationIn all its splendor, i18n is not FreeBSD-specific and is a
convention. We encourage you to help FreeBSD in following this
convention.
+ Localization settings are based on three main terms:
+ Language Code, Country Code and Encoding. Locale name constructed
+ with this three parts as follows:
+
+
+LanguageCode_CountryCode.Encoding
+
- Language Codes
+ Language and Country CodesIn order to localize a FreeBSD system to a specific language
(or any other i18n-supporting UNIX's), the user needs to find out
- the language code for the specify country and language. Country
- codes tell applications what language to use. In addition, web
+ the codes for the specify country and language (country
+ codes tell applications what variation of given
+ language to use). In addition, web
browsers, SMTP/POP servers, HTTPd's, etc. make decisions based on
- them. The following are examples of country codes:

+ Encodings
- Some languages (mostly Asian ones) use non-ASCII encodings

+ Some languages use non-ASCII encodings
+ that are 8-bit or 16-bit wide characters.
+ Older applications do not recognize
them and mistake them for control characters. Newer applications
+ usually
do recognize 8-bit characters. Depending on implementation, users
- may be required to compile the application with 8-bit support
- (such as MySQL and Apache), or configure it correctly (such as
- telnet, ssh, and system shells). To be able to input and process
- 8-bit characters, the FreeBSD Ports
+ may be required to compile an application with 16-bit support,
+ or configure it correctly.
+ To be able to input and process
+ 16-bit wide characters, the FreeBSD Ports
collection has provided each language with different
programs. Refer to the i18n documentation in the respective
FreeBSD Port.Specifically, the user needs to look at the application
documentation to decide on how to configure it correctly or to
pass correct values into the configure/Makefile/compiler.Some things to keep in mind are:
- UTF-8 encoding
+ Language specific 8-bit wide character sets, f.e.
+ ISO_8859-1, KOI8-R, CP437.
- Language specific MIME 8-bit support
+ 16-bit wide encodings, f.e. EUC, Big5.
-
- Language specific charsets
-
-
-
- UUENCODE/UUDECODE
-
+
+ You can check active list of character sets at
+ IANA Registry.
- i18n applications
+ I18n applicationsIn the FreeBSD Ports and Package system, i18n applications
have been named with i18n in their names for
easy identification. However, they do not always support the
language needed.
- Non-English users should install i18n libraries and
- applications if they wish to use a different locale.Setting LocaleTheoretically, one only needs to export the value of his/her
- language code as LANG in the login shell and is usually done
- through the user login shell configuration
- (.profile, .bashrc, or
- .cshrc). This should set all of the locale
+ locale name as LANG
+ in the login shell and is usually done
+ through the user's ~/.login_conf or
+ the user login shell configuration
+ (~/.profile, ~/.bashrc,
+ ~/.cshrc).
+ This should set all of the locale
subsets (such as LC_CTYPE,
- LC_CTIME, etc.). However, some applications
- that do not follow the i18n convention correctly will require you
- to set each locale subset specifically. Please refer to
+ LC_CTIME, etc.).
+ Please refer to
language-specific FreeBSD documentation for more
information.You should set the following two values in your configuration
files:LANG for POSIX &man.setlocale.3; family
functionsMM_CHARSET for applications' MIME character
set

+ This includes the user shell config, the specific application
config, and the X11 config.
- Setting Locale - Shell Startup Files Method
-
- There are two methods for setting locale, and both are
- described below. The first is by adding environment variables
- to the system's shell startup files, and the second is by login class. To use th first
- method, just set the two environment variables shown below in
- the /etc/profile and/or
- /etc/csh.login shell startup files. We
- will use the Russian language as an example below:
-
- In /etc/profile:
-
-
-LANG=ru_RU.KOI8-R; export LANG
-MM_CHARSET=KOI8-R; export MM_CHARSET
-
- Or in /etc/csh.login:
+ Setting Locale Methods
+
+ There are two methods for setting locale, and both are
+ described below. The first (recommended one) is by
+ setting environment variables assignment in
+ login class,
+ and the second is by adding environment variables assignment
+ to the system's shell
+ startup file.
+
+
+ Login Classes Method
+
+ This method allows to assing environment
+ variables needed for locale name and MIME character set once
+ for every possible shell instead of adding specific shell assignment
+ to each shell startup file.
+ User Level Setup
+ can be done by an user himself and
+ Administrator Level Setup require
+ superuser priviledges.
+
+
+ User Level Setup
+
+ Here is minimal example of ~/.login_conf
+ file in user's home directory which have both variables set
+ for Russian KOI8-R encoding:
-setenv LANG ru_RU.KOI8-R
-setenv MM_CHARSET KOI8-R
-
- Alternatively, you can add the above instructions to
- /usr/share/skel/dot.profile (similar to
- what was used in /etc/profile above), or
- /usr/share/skel/dot.login (similar to what
- was used in /etc/csh.login above).
-
- For X11:
-
- In $HOME/.xinitrc:
-
-
-LANG=ru_RU.KOI8-R; export LANG
-
- Or:
-
-
-setenv LANG ru_RU.KOI8-R
+me:My Account:\
+ :charset=KOI8-R:\
+ :lang=ru_RU.KOI8-R:
- Depending on your shell (see above).
+ See
+ Administrator Level Setup
+ and
+ &man.login.conf.5; for explanation.
- In $HOME/.Xresources, you can set
- application specific i18n settings (e.g., fonts, display
- characters, etc.).
-
+
-
- Login Classes
-
- This method of setting locale should only be used when you
- wish each user to be using the language you choose for your
- system. If you are a user or wish to allow users to default to
- English and change locale themselves, please disregard this
- section.
+
+ Administrator Level SetupCheck that /etc/login.conf have the
correct language user's class. Make sure these settings appear
in /etc/login.conf:
-language:Title for user accounts:\
- :charset=language charset:\
- :lang=country code.charset:\
+language_name:accounts_title:\
+ :charset=MIME_charset:\
+ :lang=locale_name:\
:tc=default:So sticking with our previous example using Russian, it
would look like this:
russian:Russian Users Accounts:\
:charset=KOI8-R:\
:lang=ru_RU.KOI8-R:\
:tc=default:
-
+ Changing Login Classes with &man.vipw.8;Use vipw to add new users, and make the
entry look like this:
user:password:1111:11:language:0:0:User Name:/home/user:/bin/sh
-
+
-
+ Changing Login Classes with &man.adduser.8;Use adduser to add new users, and do
the following:Set defaultclass = language
in /etc/adduser.conf. Keep in mind
you must enter default class for all
users of other languages in this case.An alternative variant is answering the specified
language each time that Enter login
class: default []: appears from
&man.adduser.8;Another alternative is to use the following for each
user of a different language that you wish to add:&prompt.root; adduser -class language
-
+
-
+ Changing Login Classes with &man.pw.8;If you use &man.pw.8; for adding new users, call it in
this form:
- &prompt.root; pw useradd user_name -L language
-
+ &prompt.root; pw useradd user_name -L language
+
+
+
+
+
+ Shell Startup File Method
+
+
+ This method is not recommended because require
+ different setup for each possible login program choosed.
+ Use Login Class Method
+ instead.
+
+
+ To add locale name and MIME character set
+ just set the two environment variables shown below in
+ the /etc/profile and/or
+ /etc/csh.login shell startup files. We
+ will use the Russian language as an example below:
+
+ In /etc/profile:
+
+
+LANG=ru_RU.KOI8-R; export LANG
+MM_CHARSET=KOI8-R; export MM_CHARSET
+
+ Or in /etc/csh.login:
+
+
+setenv LANG ru_RU.KOI8-R
+setenv MM_CHARSET KOI8-R
+
+ Alternatively, you can add the above instructions to
+ /usr/share/skel/dot.profile (similar to
+ what was used in /etc/profile above), or
+ /usr/share/skel/dot.login (similar to what
+ was used in /etc/csh.login above).
+
+ For X11:
+
+ In $HOME/.xinitrc:
+
+
+LANG=ru_RU.KOI8-R; export LANG
+
+ Or:
+
+
+setenv LANG ru_RU.KOI8-R
+
+ Depending on your shell (see above).

/stand/sysinstall. Once inside sysinstall,
choose Configure, then
Console. Alternatively, you can add the
following to /etc/rc.conf:

-keymap=keymap name
+scrnmap=screenmap_name
+keymap=keymap_name
+keychange="fkey_number sequence"
+
+ screenmap_name here taken from

+ without .scm suffix.
+ Screenmap with corresponding mapped font
+ is usually needed as workaround for expanding
+ 8-bit to 9-bit on VGA adapters in pseudographics area, i.e.
+ to move characters out of that area.
+
+ If you use destructive type of cursor
+ like following setting in /etc/rc.conf:
+
+
+cursor="destructive"
+
+ (see &man.vidcontrol.1;)
+ be shure that you compile your kernel with

+ 8-bit to 9-bit expansion of mouse cursor image on VGA adapters.
+
+
+ keymap_name here taken from
+ /usr/share/syscons/keymaps directory,
+ without .kbd suffix.
+
+ keychange is usually needed
+ to program function keys to match selected terminal
+ type because function keys sequences can't be defined in
+ key map.
+
+ Also be shure to set correct console terminal type in
+ /etc/ttys for all
+ ttyv* entries.

Advanced TopicsIf you wish to compile i18n applications or program i18n
compliant applications, please read this section.Compiling i18n ProgramsMany FreeBSD Ports have been ported with i18n support. Some
of them are marked with -i18n in the port name. These and many
other programs have built in support for i18n and need no special
consideration.However, some applications such as MySQL need to be have the
Makefile configured with the specific
charset. This is usually done in the
Makefile or done by passing a value to
configure in the source.Programming i18n Compliant ApplicationsTo make your application more useful for speakers of other
languages, we hope that you will program i18n compliant. The GNU
gcc compiler, GUI Libraries like QT and GTK support i18n through
special handling of strings. Making a program i18n compliant is
very easy. It allows contributors to port your application to
other languages quickly. Refer to library specific i18n
documentation for more details.To the contrary of common perception, i18n compliant code is
easy to write. Usually, it only involves wrapping your strings
with library specific functions. In addition, please be sure to
- allow for 8-bit character support.
+ allow for 16-bit wide character support.
A Call to Unify the i18n effortIt has come to our attention that the individual i18n/l10n
efforts for each country has been repeating each others'
efforts. Many of us have been reinventing the wheel repeatedly
and inefficiently. We hope that the various major groups in
i18n could congregate into a group effort similiar to the Core
Team's responsibility.Currently, we hope that, when you write or port i18n
programs, you would send it out to each country's related
FreeBSD mailing lists for testing. In the future, we hope to
create applications that work in all the languages
out-of-the-box without dirty hacks.Perl and Python
- Perl and Python have i18n and 8-bit character handling

libraries. Please use them for i18n compliance.

Please note that language support for each language varies in level.
Hence, the user should contact the respective FreeBSD local group
that is responsible for each language.The author realizes that he may have been incomplete in the
description of the i18n process in FreeBSD. Due to the various
levels of i18n implementation in both the system and applicational
levels, we advise you to refer to individual documentation, man
pages, READMEs, and so forth.Should you have any questions or suggestions regarding this
chapter, please email the author.The BasicsWhat is i18n/l10n?Developers shortened internationalization into the term i18n,
counting the number of letters between the first and the last
letters of internationalization. l10n uses the same naming

+ scheme, coming from "localization". Combined
together, i18n/l10n methods, protocols, and applications allow
users to use languages of their choice.I18n applications are programmed using i18n kits under
libraries. It allows for developers to write a simple file and
translate displayed menus and texts to each language. We strongly
encourage programmers to follow this convention.Why should I use i18n/l10n?I18n/l10n is used whenever you wish to either view, input, or
process data in non-English languages.What languages are supported in the i18n effort?I18n and l10n are not FreeBSD specific. Currently, one can
choose from most of the major languages of the World, including
but not limited to: Chinese, German, Japanese, French, Russian,
and others.Using LocalizationIn all its splendor, i18n is not FreeBSD-specific and is a
convention. We encourage you to help FreeBSD in following this
convention.

collection has provided each language with different
programs. Refer to the i18n documentation in the respective
FreeBSD Port.Specifically, the user needs to look at the application
documentation to decide on how to configure it correctly or to
pass correct values into the configure/Makefile/compiler.Some things to keep in mind are:
- UTF-8 encoding
+ Language specific 8-bit wide character sets, f.e.

- Setting Locale - Shell Startup Files Method
-
- There are two methods for setting locale, and both are
- described below. The first is by adding environment variables
- to the system's shell startup files, and the second is by login class. To use th first
- method, just set the two environment variables shown below in
- the /etc/profile and/or
- /etc/csh.login shell startup files. We
- will use the Russian language as an example below:
-
- In /etc/profile:
-
-
-LANG=ru_RU.KOI8-R; export LANG
-MM_CHARSET=KOI8-R; export MM_CHARSET
-
- Or in /etc/csh.login:
+ Setting Locale Methods
+
+ There are two methods for setting locale, and both are
+ described below. The first (recommended one) is by
+ setting environment variables assignment in
+ login class,
+ and the second is by adding environment variables assignment
+ to the system's shell
+ startup file.
+
+
+ Login Classes Method
+
+ This method allows to assing environment
+ variables needed for locale name and MIME character set once
+ for every possible shell instead of adding specific shell assignment
+ to each shell startup file.
+ User Level Setup
+ can be done by an user himself and
+ Administrator Level Setup require
+ superuser priviledges.
+
+
+ User Level Setup
+
+ Here is minimal example of ~/.login_conf
+ file in user's home directory which have both variables set
+ for Russian KOI8-R encoding:
-setenv LANG ru_RU.KOI8-R
-setenv MM_CHARSET KOI8-R
-
- Alternatively, you can add the above instructions to
- /usr/share/skel/dot.profile (similar to
- what was used in /etc/profile above), or
- /usr/share/skel/dot.login (similar to what
- was used in /etc/csh.login above).
-
- For X11:
-
- In $HOME/.xinitrc:
-
-
-LANG=ru_RU.KOI8-R; export LANG
-
- Or:
-
-
-setenv LANG ru_RU.KOI8-R
+me:My Account:\
+ :charset=KOI8-R:\
+ :lang=ru_RU.KOI8-R:
- Depending on your shell (see above).
+ See
+ Administrator Level Setup
+ and
+ &man.login.conf.5; for explanation.
- In $HOME/.Xresources, you can set
- application specific i18n settings (e.g., fonts, display
- characters, etc.).
-
+
-
- Login Classes
-
- This method of setting locale should only be used when you
- wish each user to be using the language you choose for your
- system. If you are a user or wish to allow users to default to
- English and change locale themselves, please disregard this
- section.
+
+ Administrator Level SetupCheck that /etc/login.conf have the
correct language user's class. Make sure these settings appear
in /etc/login.conf:
-language:Title for user accounts:\
- :charset=language charset:\
- :lang=country code.charset:\
+language_name:accounts_title:\
+ :charset=MIME_charset:\
+ :lang=locale_name:\
:tc=default:So sticking with our previous example using Russian, it
would look like this:
russian:Russian Users Accounts:\
:charset=KOI8-R:\
:lang=ru_RU.KOI8-R:\
:tc=default:
-
+ Changing Login Classes with &man.vipw.8;Use vipw to add new users, and make the
entry look like this:
user:password:1111:11:language:0:0:User Name:/home/user:/bin/sh
-
+
-
+ Changing Login Classes with &man.adduser.8;Use adduser to add new users, and do
the following:Set defaultclass = language
in /etc/adduser.conf. Keep in mind
you must enter default class for all
users of other languages in this case.An alternative variant is answering the specified
language each time that Enter login
class: default []: appears from
&man.adduser.8;Another alternative is to use the following for each
user of a different language that you wish to add:&prompt.root; adduser -class language
-
+
-
+ Changing Login Classes with &man.pw.8;If you use &man.pw.8; for adding new users, call it in
this form:
- &prompt.root; pw useradd user_name -L language
-
+ &prompt.root; pw useradd user_name -L language
+
+
+
+
+
+ Shell Startup File Method
+
+
+ This method is not recommended because require
+ different setup for each possible login program choosed.
+ Use Login Class Method
+ instead.
+
+
+ To add locale name and MIME character set
+ just set the two environment variables shown below in
+ the /etc/profile and/or
+ /etc/csh.login shell startup files. We
+ will use the Russian language as an example below:
+
+ In /etc/profile:
+
+
+LANG=ru_RU.KOI8-R; export LANG
+MM_CHARSET=KOI8-R; export MM_CHARSET
+
+ Or in /etc/csh.login:

Advanced TopicsIf you wish to compile i18n applications or program i18n
compliant applications, please read this section.Compiling i18n ProgramsMany FreeBSD Ports have been ported with i18n support. Some
of them are marked with -i18n in the port name. These and many
other programs have built in support for i18n and need no special
consideration.However, some applications such as MySQL need to be have the
Makefile configured with the specific
charset. This is usually done in the
Makefile or done by passing a value to
configure in the source.Programming i18n Compliant ApplicationsTo make your application more useful for speakers of other
languages, we hope that you will program i18n compliant. The GNU
gcc compiler, GUI Libraries like QT and GTK support i18n through
special handling of strings. Making a program i18n compliant is
very easy. It allows contributors to port your application to
other languages quickly. Refer to library specific i18n
documentation for more details.To the contrary of common perception, i18n compliant code is
easy to write. Usually, it only involves wrapping your strings
with library specific functions. In addition, please be sure to
- allow for 8-bit character support.
+ allow for 16-bit wide character support.
A Call to Unify the i18n effortIt has come to our attention that the individual i18n/l10n
efforts for each country has been repeating each others'
efforts. Many of us have been reinventing the wheel repeatedly
and inefficiently. We hope that the various major groups in
i18n could congregate into a group effort similiar to the Core
Team's responsibility.Currently, we hope that, when you write or port i18n
programs, you would send it out to each country's related
FreeBSD mailing lists for testing. In the future, we hope to
create applications that work in all the languages
out-of-the-box without dirty hacks.Perl and Python
