Guestbook Issues

Hi everyone,

I can't type hiragana at work so this will have to be an English post.

It seems the guestbook at the bottom of the page doesn't like Japanese characters very much. They all come out as these weird unicode symbols. Thanks to Melissa and Hein for leaving comments, but I can't see what they are (Q_Q). The regular comments should be able to show the hiragana without any trouble so I'm probably just going to get rid of the guestbook.
