Language as a Validation Rule?

[mashuu83]

I am trying to make a simple database for studying Japanese language and just for fun! I would like to try to make a validation rule for some of my cells that only allows the user to input Kanji characters (i.e. 漢字) in certain fields, katakana (i.e. カタカナ) in some fields and hiragana　(i.e. ひらがな) in others. Is there any way to do this? Thanks~
