I18N_Collate

# 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 = new I18N::Collate "scalar_data_1";
        $s2 = new I18N::Collate "scalar_data_2";

# DESCRIPTION

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 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. Due to `cmp` and overload magic, `lt`, `le`, `eq`, `ge`, and `gt` work also. The available locales depend on your operating system; try whether Cls /usr/lib/nls/loc or CThe 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.
