Edit: I've narrowed it down to the following byte sequence. I can't seem to remove any of the characters without it no longer crashing: 00000000 d9 88 d2 88 cd a5 cd a8 cd aa cd af 20 d2 88 d2 |............ ...|
00000010 88 d2 88 |...|

U+0368 COMBINING LATIN SMALL LETTER C character (ͨ)
U+036A COMBINING LATIN SMALL LETTER H character (ͪ)
U+036F COMBINING LATIN SMALL LETTER X character (ͯ)
U+0020 SPACE character
U+0488 COMBINING CYRILLIC HUNDRED THOUSANDS SIGN character (҈)
U+0488 COMBINING CYRILLIC HUNDRED THOUSANDS SIGN character (҈)
U+0488 COMBINING CYRILLIC HUNDRED THOUSANDS SIGN character (҈)Can someone explain what is happening and why the tweet is affecting the tab and this post does not?
In the end both just render unicode characters. And it looks like only Firefox is able to display it correctly on OSX 10.8.

I'm not familar enough with CoreText internals to guess what's going wrong, though. :)Interesting bug.
minimalist example:
data:text/html;charset=utf-8,<p style='font-family: "Times New Roman";'>%D9%88%20%D2%88%D2%88%D2%88
It seems to be a problem with utf-8 vs. unicode + Times New Roman.tested on: Chrome 24.0.1312.57 | OS x 10.8.2
Edit: also works with other fonts for example Arial
Nah, just kidding.
Chrome 24.0.1312.57 | OS x 10.8.2
OS X 10.8.2 (12C60)
Cool.

Edit: Apparently it is only the unicode
