Hi,
MySQL does not afaik support unicode characters (I have been trying to do something similar recently.)
You can use HTML extended characters to try to store the language within a normal textfield, bearing in mind that each 'extended' character will take up 6 normal ASCII characters when storing in a text type field.
(an extended character looks like: &10203; or somesuch - If using a webbrowser to view these characters, you will need the correct language pack installed.)
Hope that helps,
