I18N::Collate - compare 8-bit scalar data according to the current locale
use I18N::Collate; setlocale(LC_COLLATE, 'locale-of-your-choice'); $s1 = I18N::Collate->new("scalar_data_1"); $s2 = I18N::Collate->new("scalar_data_2");
*** WARNING: starting from the Perl version 5.003_06 the I18N::Collate interface for comparing 8-bit scalar data according to the current locale HAS BEEN DEPRECATED 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. See the perllocale manual page for further information. ***
This module provides you with objects that will collate according to your national character set, provided that the POSIX setlocale() function is supported on your system.
You can compare $s1 and $s2 above with
$s1 le $s2
to extract the data itself, you'll need a dereference: $$s1
This module uses POSIX::setlocale(). The basic collation conversion is done by strxfrm() which terminates at NUL characters being a decent C routine. collate_xfrm() handles embedded NUL characters gracefully.
The available locales depend on your operating system; try whether
locale -ashows them or man pages for "locale" or "nlsinfo" or the direct approach
ls /usr/lib/locale. 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
xx_XX.(ISO)?8859N, for example
fr_CH.ISO8859-1is the Swiss (CH) variant of French (fr), ISO Latin (8859) 1 (-1) which is the Western European character set.
