After merging #3646 I see a bunch of failures like this one with python 3.4.1:

----------------------------------------------------------------------

I.e. a large number of pdf tests using fonts fails. Not sure why travis doesn't hit this.

This is on OSX 10.10 with python installed from homebrew. The tests passes with Python 2.7

I did not test with python 3 before the merge.

It probably occurs with a specific font on your system. Travis has very few fonts installed.

It would be helpful to know what this font is -- print out "font.fname" on the line above.

Looks like CharacterComplement doesn't return a unicode string so make it a bytestring in python3
