 Getting a pretty obscure bug with TinyMCE in certain situations. Turning
 on bold text either with the toolbar button or Ctrl-B then starting to
 type, Chrome 38 will crash with the first keystroke.

 It's possibly a Chrome issue - it's only come to light with Chrome 38
 released last week and isn't (currently) happening with Chrome Canary 40,
 however it's only happening in WordPress, not with straight TinyMCE and
 most notably, only when using the Twenty Twelve theme (or children of it).

 Here's the bug in action:

 I'm almost certain it has something to do with the U+FEFF (ZERO WIDTH NO-
 BREAK SPACE / BYTE ORDER MARK) character that gets inserted when bold text
 is turned on as they cause crashes in the frontend of WordPress sites as
 well.
