Japanese kanji: Mac OS X vs SDMB

There have been a few occasions when I have wanted to post a bit of Japanese kanji to the board. When I type it into the box, it looks fine. When I hit “Submit New Thread”, however, the board converts it into nonsense. I see other posters having success with this; why can’t I do it? Is vBulletin Mac-averse?

Okay, never mind then. I changed the text encoding to Unicode before I submitted that post, and it worked. I’ll make a note for next time. Sorry for the bother.
