#NAME
locale - Perl pragma to use or avoid POSIX locales for built-in operations
#SYNOPSIS
my @x1 = sort @y; # Native-platform/Unicode code point sort order
{
use locale;
my @x2 = sort @y; # Locale-defined sort order
}
my @x3 = sort @y; # Native-platform/Unicode code point sort order
# again
# Parameters to the pragma are to work around deficiencies in locale
# handling that have since been fixed, and hence these are likely no
# longer useful
use locale qw(:ctype :collate); # Only use the locale for character
# classification (\w, \d, etc.), and
# for string comparison operations
# like '$a le $b' and sorting.
use locale ':not_characters'; # Use the locale for everything but
# character classification and string
# comparison operations
use locale ':!numeric'; # Use the locale for everything but
# numeric-related operations
use locale ':not_numeric'; # Same
no locale; # Turn off locale handling for the remainder of
# the scope.#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.
The pragma is documented as part of perllocale.
