Never mind. I got it working. I had to include a PHP file that was saved in unicode in order for it to display unicode characters on the page. So it was a PHP issue and not a MySQL issue after all.
I don't have an opinion about whether or not non-standard Lojban should be allowed on jboselkei. I think we should probably put it to a vote. Whatever people here decide on, I'll put a notice on the website.
