NAME

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

SYNOPSIS

  1. @x = sort @y; # ASCII sorting order
  2. {
  3. use locale;
  4. @x = sort @y; # Locale-defined sorting order
  5. }
  6. @x = sort @y; # ASCII sorting order again

DESCRIPTION

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.

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