The term 'DBCS' is not sufficient to determine what the encoding of
your input character set is. That could mean any of a large number of
mutually incompatible character encodings: UTF-16, Big5, Shift-JIS
(for Japanese), and EUC-CN are only a few of the possibilities. Before
you can even begin to process any text you get from anywhere, it's
just a stream of bytes with no meaning until you know what its
encoding is. You can't perform any kind of useful text processing
without knowing the encoding.

Once you do know the encoding, you should probably convert it to UTF-8
using the Iconv library, and you should probably be able to do
something useful with the text.

Also, make sure that $KCODE is 'u'. Otherwise Unicode text processing
will not work.
