On one MSE question, the comments are overlapping the related questions sidebar. Is this something to do with the weird formatting of the first comment?

I see this on Firefox indeed, and not on Chrome. You really want to include browser information in your report, as well as a link to the post. –  Martijn Pieters Nov 6 '12 at 12:26

This is due to the strike preventing work wrap. This is NOT real strike, those are unicode character combined. –  Shadow Wizard Nov 6 '12 at 12:29

@MartijnPieters. Thanks. Silly of me. Should have included that link to start with. –  TRiG is Timothy Richard Green Nov 6 '12 at 12:32

Well, since comments won't allow the ordinary strike formatting, someone there tried (and succeeded!) to trick the system by combining Unicode characters resembling English letters with a strike through them.

This results in one long stream of characters without any blank space, no different than:

sincecommentswon'tallowtheordinary<strike>strike</strike>formattingsomeonetheretried(andsucceeded!)totrickthesystembycombiningunicodecharacters

Each browser handles such things in its own way; I don't think there's much to be done.

Just in case, here is the culprit string of characters:

P̶o̶s̶s̶i̶b̶l̶y̶ ̶[̶W̶e̶b̶ ̶A̶p̶p̶s̶]̶(̶h̶t̶t̶p̶:̶/̶/̶w̶e̶b̶a̶p̶p̶s̶.̶s̶t̶a̶c̶k̶e̶x̶c̶h̶a̶n̶g̶e̶.̶c̶o̶m̶/̶)‌​̶,̶ ̶b̶u̶t̶ ̶s̶i̶n̶c̶e̶ ̶w̶h̶a̶t̶ ̶y̶o̶u̶'̶r̶e̶ ̶a̶s̶k̶i̶n̶g̶ ̶f̶o̶r̶ ̶i̶s̶ ̶l̶i̶k̶e̶l̶y̶ ̶t̶o̶ ̶b̶e̶ ̶s̶a̶t̶i̶s̶f̶i̶e̶d̶ ̶b̶y̶ ̶a̶ ̶b̶r̶o̶w̶s̶e̶r̶ ̶p̶l̶u̶g̶i̶n̶ ̶o̶r̶ ̶p̶r̶o̶x̶y̶,̶ ̶I̶'̶d̶ ̶s̶a̶y̶ ̶t̶r̶y̶ ̶S̶U̶

If you run the above through an ASCII converter (this one was built from scratch just now, as I didn't find any decent converter online) you will see there is no blank space but rather a character with ASCII value 822 following each letter.
