<PRE>
WARNING: starting from the Perl version 5.003_06
the I18N::Collate interface for comparing 8-bit scalar data
according to the current locale</PRE>
<PRE>
HAS BEEN DEPRECATED</PRE>
<PRE>
That is, please do not use it anymore for any new applications
and please migrate the old applications away from it because its
functionality was integrated into the Perl core language in the
release 5.003_06.</PRE>
<PRE>
See the <A HREF="../../lib/Pod/perllocale.html">perllocale</A> manual page for further information.</PRE>

use I18N::Collate;
setlocale(LC_COLLATE, 'locale-of-your-choice');
$s1 = new I18N::Collate "scalar_data_1";
$s2 = new I18N::Collate "scalar_data_2";</PRE>

<H1><A NAME="description">DESCRIPTION</A></H1>
<P>This module provides you with objects that will collate
according to your national character set, provided that the
POSIX <CODE>setlocale()</CODE> function is supported on your system.</P>
<P>You can compare $s1 and $s2 above with</P>
<PRE>
$s1 le $s2</PRE>
<P>to extract the data itself, you'll need a dereference: $$s1</P>
<P>This module uses POSIX::setlocale(). The basic collation conversion is
done by <CODE>strxfrm()</CODE> which terminates at NUL characters being a decent C
routine. <CODE>collate_xfrm()</CODE> handles embedded NUL characters gracefully.</P>
<P>The available locales depend on your operating system; try whether
<CODE>locale -a</CODE> shows them or man pages for ``locale'' or ``nlsinfo'' or the
direct approach <CODE>ls /usr/lib/nls/loc</CODE> or <CODE>ls /usr/lib/nls</CODE> or
<CODE>ls /usr/lib/locale</CODE>. Not all the locales that your vendor supports
are necessarily installed: please consult your operating system's
documentation and possibly your local system administration. The
locale names are probably something like <CODE>xx_XX.(ISO)?8859-N</CODE> or
<CODE>xx_XX.(ISO)?8859N</CODE>, for example <CODE>fr_CH.ISO8859-1</CODE> is the Swiss (CH)
variant of French (fr), ISO Latin (8859) 1 (-1) which is the Western
European character set.</P>
