So, if you try to put something non-Standard into the title field, it accepts it, but then doesn't print it correctly and just leaves it as the unconverted unicode. At least, I assume that's what the issue is. For example:
最後にはどうか... 幸せな記憶を... (quote from Air) goes in fine and turns your title into a board stretching monstrosity.

And even as I preview it, I see that it's getting parsed into the proper Unicode stuff, but apparently the title has that disabled or something even though the field accepts is as valid input.

I mean, uh, not good!
Please don't do that then.
It's not in the rules! Time to go on a reign of terror!
Or eat some delicious muffins.
Maaan. Decisions.
