Here's a function that, given a `str` containing a vcard in some
encoding, guesses the encoding and returns a canonical representation
as a `unicode` object.

def fix_encoding(s):
    m = u'BEGIN:VCARD'
    for c in ('ascii', 'utf_16_be', 'utf_16_le', 'utf_8'):
        try: u = unicode(s, c)
        except UnicodeDecodeError: continue
        if m in u: return u
    return None
