locale - Perl pragma to use and avoid POSIX locales for built-in opera-
@x = sort @y; # ASCII sorting order
@x = sort @y; # Locale-defined sorting order
@x = sort @y; # ASCII sorting order again
See perldoc locale and perldoc perllocale, and set your LANG environment
variable, methinks. IIRC there's something like the 'he_IL.UTF8' locale
on most GNU operating systems.
Alternatively you can probably 'use utf8' for literals if your perl is
old, and make sure the data you insert is (using perlio layers, etc)
indeed UTF8 strings in perl. A recent perl should work as you expect,
unless you 'use bytes'.
