Public bug reported:
When using DateFormatter with umlauts in month names, a
UnicodeDecodeError is raised:
months_formatter = matplotlib.dates.DateFormatter('%b')
axes.xaxis.set_major_formatter(months_formatter)
and the German month name "März" lead to
Traceback (most recent call last):

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 1:

By the way, the month name is also truncated to "M??r" because the "ä"
takes two bytes, prolonging the month name by one byte.
