When I edited the D:OS 360?ー rotation topic (update paths after profile support added) the degree symbol got a couple extra symbols inserted. This started after the forum software update, but Larian hasn't had a lot of time to look into it.
Even if I cut and paste 360ー from the topic, where it is displayed fine (and in the preview), when I post it gets changed, so Word isn't the problem directly (or at least not entirely).
