This uses syntax to determine the direction of encoding. It would be
easier and clearer to just require two arguments or a tuple.
u = unicode(b, 'encode', 'base64')
b = bytes(u, 'decode', 'base64')
b = bytes(u, 'encode', 'utf-8')
u = unicode(b, 'decode', 'utf-8')
u2 = unicode(u1, 'encode', 'piglatin')
u1 = unicode(u2, 'decode', 'piglatin')
It looks somewhat cleaner if you combine them in a path style string.
b = bytes(u, 'encode/utf-8')
u = unicode(b, 'decode/utf-8')
