101<p>
102A Locale is a set of information that most programs use for determining
103country and language specific settings. The locales and their data
104are part of the system library and can be found
105at <path>/usr/share/locale</path> on most systems. A locale name is generally
106named <c>ab_CD</c> where <c>ab</c> is your two (or three) letter
107language code (as specified in ISO-639) and <c>CD</c> is your two letter country
108code (as specified in ISO-3166).

114<title>Environment variables for locales</title>
94<body> 115<body>
95 116
96<p>
97The next step is to set the <c>LANG</c> shell variable, which
98is used by your shell and window manager (and some other
99applications). Valid values can be found in
100<path>/usr/share/locale</path> and generally take the form
101<c>ab_CD</c>, where <c>ab</c> is your two letter language code
102and <c>CD</c> is your two letter country code. The <c>_CD</c>
103is left off if your language is only (or primarily) spoken in
104one country. <c>LANG</c> can be set in
105<path>/etc/profile</path> if you want it to take effect
106system-wide, or in <path>~/.bashrc</path> as a user-specific
107setting.
108</p> 117<p>
118Locale settings are stored in environment variables. These are typically
119set in the <path>/etc/env.d/02locale</path> (for system-wide
120settings) and <path>~/.bashrc</path> (for user-specific settings) file.
121The variables controlling different aspects of locale settings
122are given in the table below, those with highest precedence (i.e. those
123that override settings below them) are at the top of the table. All variables
124take one name of a locale in <c>ab_CD</c> format given above.

190<note>
191Even though most programs work with LC_ALL only, some of them misbehave if
192LC_ALL is set but LANG isn't. If you want to play safe, set them <e>both</e>.
193</note>
194
195<p>
196Most typically users only set the LANG variable and perhaps LC_CTYPE variable
197on user level by adding definitions to shells startup files defining
198the environment variable manually from command line:
199</p>

116currency symbol (&#8364;) 207currency symbol ()
117</note> 208</note>
209
210<p>
211It is also possible to set a system-wide locale for all users and programs:
212</p>
213
214<pre caption="Setting the default system locale in /etc/env.d/02locale">
215LC_ALL="de_DE@euro"
216LANG="de_DE@euro"
217</pre>
218
219<p>
220A common practice is to use only per user locale settings and leave the
221default system locale unset. In this case system locale defaults to a
222special value <c>"C"</c>, which for historical reasons maps to the English
223locale.
224</p>
225
226<p>
227For message based localization to work in programs that support it, you will
228probably need to have programs compiled with the <c>nls</c> (Native language
229support) USE flag set. Most of the programs using nls also need the gettext
230library to extract and use localized messages. Of course, Portage will
231automatically install it when needed.
232</p>
233
234<p>
235Once you have set the right locale, be sure to update your environment
236variables to make your system aware of the change:
237</p>
238
239<pre caption="Update the environment">
240<comment>(For system-wide default locale:)</comment>
241# <i>env-update &amp;&amp; source /etc/profile</i>
242
243<comment>(For user-specific locale:)</comment>
244$ <i>source ~/.bashrc</i>
245</pre>
246
247<p>
248After this, you will need to kill your X server by pressing
249<c>Ctrl-Alt-Backspace</c>, log out, then log in as user.
250</p>
251
252<p>
253Now, verify that the changes have taken effect:
254</p>
255
256<pre caption="Verify env changes">
257$ <i>env | grep -i LC_</i>
258</pre>
259
260<p>
261There is also additional localisation variable called LINGUAS, which affects
262to localisation files that get installed in gettext-based programs, and decides
263used localisation for some specific software packages, such as
264<c>kde-base/kde-i18n</c> and <c>app-office/openoffice</c>. The variable
265takes in <e>space</e>-separated list of language codes, and suggested
266place to set it is <path>/etc/make.conf</path>:
267</p>
268
269<pre caption="Setting LINGUAS in make.conf">

394If you have an international keyboard layout, you should set the option
395<c>XkbModel</c> to <c>pc102</c> or <c>pc105</c>, as this will allow mapping of the
396additional keys specific to your keyboard.
397</p>
398
399<p>
400Deadkeys allow you to press keys that will not show immediately but will be
401combined with another letter to produce a single character such as é,è,á,à,

403characters into X terminals.

406<p>
407If you would like to switch between more than one keyboard layout (for example
408English and Russian), all you have to do is add a few lines to

410command.
