Well I don't know wether anyone else have had this problem . but all kint of special characters get changed into really weird things, for example my userpage got kint of screwed up it changed all my spaces and commas in question markes. and some characters in threads and posts get changed to:
Animé = well anime with the a stripe above it
on my userpage and one of my threads it changes in somekint of chinese character. I saw this problem in some submission
names too.
