When I attempt to run the histogram demo using Python 3 + matplotlib 1.2, I get this traceback:

Exception in Tkinter callback

    for match in _fc_match_regex.finditer(output):
TypeError: can't use a string pattern on a bytes-like object

Upon setting USE_FONTCONFIG = False in font_manager.py, it worked. Not sure which one is the issue here.

@tomspur

This will be fixed, once issue #1879 is solved.

It looks like #1879 and #1921 were resolved. This should be resolved now, so I'll close it.

@amitsaha If I am mistaken and this is still a problem for you, please feel free to reopen this issue.
