When creating a wiki/character page that has a title with special characters, you can't use the link buttons, and have to use a url instead.
I tried replacing the characters in the link with URL and HTML encoded versions, but that doesn't work either.
So far I know of two characters causing this problem:& and '
but my guess is there are others as well.
It looks like you're new here. If you want to get involved, click one of these buttons!
