<indexterm><primary>internationalizationand fonts</primary></indexterm>
<para>The user usually changes fonts using Style Manager, which in turn restarts
Workspace Manager, resetting the desktop fonts. You can also customize fonts
at the command line or in resource files. In an internationalized environment,
the user must specify fonts that are independent of the code set. This is
necessary because the specification can be used under various locales with
different code sets than the character set (<symbol role="Variable">charset</symbol>)
of the font. Therefore, all font lists should be specified with
a font set.</para>
<sect2 id="UG.uI18N.div.8">
<title>Font Specification</title>
<para>A <emphasis>font specification</emphasis> within a fontlist can be
either an X Logical Function Description (XLFD) name or an alias for the
XLFD name. For example, the following are valid font specifications for
a 14-point font:
</para>
<indexterm><primary>font specification</primary></indexterm>
<indexterm><primary>XLFD</primary></indexterm>
<programlisting>-dt-interface system-medium-r-normal-serif-*-*-*-*-p-*-iso8859-1
<emphasis>Or,</emphasis> -*-r-*-14-*iso8859-1</programlisting>
</sect2>
<sect2 id="UG.uI18N.div.9">
<title>Font Set Specification</title>
<para>The <emphasis>font set specification</emphasis> within a fontlist is a list of XLFD names
or their aliases (sometimes called a <emphasis>base name list</emphasis>).
The names are separated by semi-colons, and any blank space before or after
the semi-colon is ignored. Pattern- matching (wildcard) characters can be
specified to help shorten XLFD names.</para>
<indexterm><primary>font set specification</primary></indexterm>
<indexterm><primary>base name font list</primary></indexterm>
<para>A font set specification is determined by the locale that is running.
For example, the Japanese locale defines three fonts (character sets) necessary
to display all of its characters. The following example identifies the set
of Mincho fonts needed.</para>
<itemizedlist remap="Bullet1"><listitem><para>Sample name list with character
set:</para>
<programlisting>-dt-interface system-medium-r-normal-serif-*-*-*-*-p-*-14;

</programlisting>
</listitem><listitem><para>Sample single pattern name without character set:
</para>
<programlisting>-dt-*-medium-*-24-*-m-*:

<para>The preceding two cases can be used with a Japanese locale as long as
there are fonts that match the base name list.</para>
