Summary: calendar.weekheader(n): n should mean chars not bytes

Initial Comment:
calendar.weekheader(n) is locale aware, which is good
in principle. The parameter n, however, is interpreted
as meaning bytes, not chars, which can generate broken
strings for, e.g. localized weekday names:

>>> calendar.weekheader(2)
'Mo Tu We Th Fr Sa Su'
>>> locale.setlocale(locale.LC_ALL, "pt_BR.UTF-8")
'pt_BR.UTF-8'
>>> calendar.weekheader(2)
'Se Te Qu Qu Se S\xc3 Do'

Notice how "Sábado" (Saturday) above is missing the
second utf-8 byte for the encoding of "á":

>>> u"Sá".encode("utf-8")
'S\xc3\xa1'

The implementation of weekheader (and of all of
calendar.py, it seems) is based on localized 8 bit
strings. I suppose the correct fix for this bug will
involve a roundtrip thru unicode.
