=head1 DESCRIPTION

PerlÀÇ ¼¼°è¿¡ ¿À½Å °ÍÀ» ȯ¿µÇÕ´Ï´Ù !

Starting for Perl release 5.8.0 Perl has extensive support for Unicode
and as a part of that, extensive support for non-Latin characters
encodings, including the CJK (Chinese-Japanese Korean).  Unicode is an
international standard that aims to include all of world's
characters: Western, Eastern, and everything in between (Greek,
Cyrillic, Arabic, Hebrew, Indic, Amerindian, and so on), and
encodings of various operating system platforms (PC and MacIntosh).
