NAME
I18N::Collate - compare 8-bit scalar data according to the current locale
SYNOPSIS
use I18N::Collate; setlocale(LC_COLLATE, locale-of-your-choice); $s1 = I18N::Collate->new(“scalar_data_1”); $s2 = I18N::Collate->new(“scalar_data_2”);
DESCRIPTION
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 -a shows them or man pages for locale or nlsinfo or the direct
approach ls /usr/lib/nls/loc or ls /usr/lib/nls or
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)?8859-N or
xx_XX.(ISO)?8859N, for example fr_CH.ISO8859-1 is the Swiss (CH)
variant of French (fr), ISO Latin (8859) 1 (-1) which is the Western
European character set.
