 feedback, this is not my area.

 The filter is precombining the characters just before save, so an
 additional normalization on paste in TinyMCE would be beneficial, because
 until the post is not saved you have a broken proofread, search, etc.

 I don't know if we should add this with a check for PHP 5.3 in core,
 because I don't know if this check for Normalization Form C is a
 performance problem, so I added the "needs testing" tag.

 Maybe some more advanced PHP devs can have a look at this for the
 performance question. I mean, it solves a '''Mac-only''' problem which is
 just there if you copy&paste from a PDF. I wouldn't add a normalization
 just for this case if it would slow down all other sites without any
 reason.
