Don't have any good answer for this, more than take a look at the mysql
documentation, http://dev.mysql.com/doc/refman/5.0/en/charset-unicode.html
For sure if you try to store utf-8 characters in an iso-8859-1 table, you will
waste up the space a lot faster for cjk text. If using utf-8/ucs-2, then one
character should logically take one space, no matter if it's one-byte
sequence, two-byte sequence or three-byte sequence.
alt.php.sql had IMHO been a lot better newsgroup to ask this question.
