Exception with accentuated characters in user.name

[guillemglez]

When set user.name includes accents, repo init throws an exception:

Traceback (most recent call last):
  File ".repo/repo/main.py", line 547, in <module>
    _Main(sys.argv[1:])
  File ".repo/repo/main.py", line 522, in _Main

    d = d.decode('utf-8')
  File "/usr/lib/python2.7/encodings/utf_8.py", line 16, in decode
    return codecs.utf_8_decode(input, errors, True)
UnicodeDecodeError: 'utf8' codec can't decode byte 0xe1 in position 22: invalid continuation byte

To solve it, user.name has to be changed with A-z characters:
git config --global user.name "Your Name"
