Windows 7, Python 2.7

Some windows applications (QuickTime) add content-types to Windows registry with non-ascii names. mimetypes in unaware of that and fails with UnicodeDecodeError:

>>> mimetypes.guess_type('test.js')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "c:\Python27\lib\mimetypes.py", line 294, in guess_type
    init()
  File "c:\Python27\lib\mimetypes.py", line 355, in init
    db.read_windows_registry()
  File "c:\Python27\lib\mimetypes.py", line 260, in read_windows_registry
    for ctype in enum_types(mimedb):
  File "c:\Python27\lib\mimetypes.py", line 250, in enum_types
    ctype = ctype.encode(default_encoding) # omit in 3.x!
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe0 in position 0: ordinal not in range(128)

Example registry leaf is attached to previous message.

I believe the correct behavior would be either to wrap UnicodeDecodeError exception and skip those content-typer or use .decode() method for registry keys and get encoding using locale.getdefaultlocale()
