bytes regex matching issue in font_manager.py around 1283 (line number)

for match in _fc_match_regex.finditer(output):

the 'output' is a byte array, but expected is string runtime type-error, 

i think this issue might already have been raised. I am using python3-mapltplotlib-tk backend on fedora 18. I am not sure if it is fixed or not.

THE FIX(atleast for me):
I change the above line to (I changed the byte array to utf-8 string)
for match in _fc_match_regex.finditer(output.decode("utf-8")):
and I am able to plot.No type-error
