[Plugin: Comprehensive Google Map Plugin] How to make location field free

I love CGMP!

I’m trying this to use in Japanese (with Chinese characters), I cannot…
(ex) 東京

It can use Roman characters.
(ex) Tokyo

I think one of temporary avoidances that I turn off location field’s alart.
Please tell me how to make location field free or something to use with Chinese characters address!!
