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

	 ***

	 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() func-
       tion 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 nec-
       essarily 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.

NAME

       locale - Perl pragma to use or avoid POSIX locales for built-in operations

SYNOPSIS

	   @x = sort @y;       # Unicode sorting order
	   {
	       use locale;
	       @x = sort @y;   # Locale-defined sorting order
	   }
	   @x = sort @y;       # Unicode sorting order again

DESCRIPTION

       This pragma tells the compiler to enable (or disable) the use of POSIX locales for built-in operations (for example, LC_CTYPE for regular
       expressions, LC_COLLATE for string comparison, and LC_NUMERIC for number formatting).  Each "use locale" or "no locale" affects statements
       to the end of the enclosing BLOCK.

       Starting in Perl 5.16, a hybrid mode for this pragma is available,

	   use locale ':not_characters';

       which enables only the portions of locales that don't affect the character set (that is, all except LC_COLLATE and LC_CTYPE).  This is
       useful when mixing Unicode and locales, including UTF-8 locales.

	   use locale ':not_characters';
	   use open ":locale";		 # Convert I/O to/from Unicode
	   use POSIX qw(locale_h);	 # Import the LC_ALL constant
	   setlocale(LC_ALL, "");	 # Required for the next statement
					 # to take effect
	   printf "%.2f
", 12345.67'	 # Locale-defined formatting
	   @x = sort @y;		 # Unicode-defined sorting order.
					 # (Note that you will get better
					 # results using Unicode::Collate.)

       See perllocale for more detailed information on how Perl supports locales.

NOTE

       If your system does not support locales, then loading this module will cause the program to die with a message:

	   "Your vendor does not support locales, you cannot use the locale
	   module."
