I tried to post a stack trace which contained some Swedish letters.
When posting and then viewing it I could see that the post abruptly ended just before the first Swedish character.
Editing the post showed it was just cut and everything from that point was gone, so I had to click "back" in the browser a few times to get to where I was actually posting it the first time and I could find my entire post there and copy it. I then had to click to get to the forum, click on my post, paste my original post and edit it to remove all the Swedish characters (missed a couple a few times so had to do it like 3-4 times...) and save it.
Rather annoying.
