locale - Perl pragma to use and avoid
POSIX locales for built-in operations
@x = sort @y; # ASCII sorting order
{
use locale;
@x = sort @y; # Locale-defined sorting order
}
@x = sort @y; # ASCII sorting order again
This pragma tells the compiler to enable (or disable) the use of
POSIX locales for built-in operations
(LC_CTYPE for regular expressions, and
LC_COLLATE for string comparison). Each ``use locale'' or ``no locale'' affects statements to the end of the enclosing
BLOCK.
