Looks up the <link linkend="PangoScript"><type>PangoScript</type></link> for a particular character (as defined by
Unicode Standard Annex <link linkend="24:CAPS"><type>24</type></link>). No check is made for <parameter>ch</parameter> being a
valid Unicode character; if you pass in invalid character, the
result is undefined.</para>

<para>
Given a script, finds a language tag that is reasonably
representative of that script. This will usually be the
most widely spoken or used language written in that script:
for instance, the sample language for <link linkend="PANGO-SCRIPT-CYRILLIC:CAPS"><literal>PANGO_SCRIPT_CYRILLIC</literal></link>
is <literal>ru</literal> (Russian), the sample language
for <link linkend="PANGO-SCRIPT-ARABIC:CAPS"><literal>PANGO_SCRIPT_ARABIC</literal></link> is <literal>ar</literal>.
</para>
<para>
For some
scripts, no sample language will be returned because there
is no language that is sufficiently representative. The best
example of this is <link linkend="PANGO-SCRIPT-HAN:CAPS"><literal>PANGO_SCRIPT_HAN</literal></link>, where various different
variants of written Chinese, Japanese, and Korean all use
significantly different sets of Han characters and forms
of shared characters. No sample language can be provided
for many historical scripts as well.</para>

<para>
Determines if <parameter>script</parameter> is one of the scripts used to
write <parameter>language</parameter>. The returned value is conservative;
if nothing is known about the language tag <parameter>language</parameter>,
<link linkend="TRUE:CAPS"><literal>TRUE</literal></link> will be returned, since, as far as Pango knows,
<parameter>script</parameter> might be used to write <parameter>language</parameter>.
</para>
<para>
This routine is used in Pango's itemization process when
determining if a supplied language tag is relevant to
a particular section of text. It probably is not useful for
applications in most circumstances.</para>
