for multibyte character

Hello, I'm setofumi from Japan. I found your impressive "written?kitten!" and I'd like to use in the multibyte character environment. I modified your source code and upload the file below.

I'll translate "about" and the notification for local storage information into Japanese.

Please let me know if you don't like this modification and introduction in Japanese.
