Column lengths incorrect using multi-byte charsets in MySQL

[ChrisBlackwell]

There is a problem with the MySQL ObjectDAO when using multi-byte character sets, returning an incorrect length for the field. This causes validation errors with char, varchar and enum fields.

The readFields() method incorrectly uses CHARACTER_MAXIMUM_LENGTH when i believe it should use CHARACTER_OCTET_LENGTH.

From - http://dev.mysql.com/doc/refman/5.0/en/columns-table.html

CHARACTER_OCTET_LENGTH should be the same as CHARACTER_MAXIMUM_LENGTH, except for multi-byte character sets.
