It seems also the error messages aren't too helpful:
>>> "ä".encode("latin-1")
Traceback (most recent call last):
File "<stdin>", line 1, in ?
UnicodeDecodeError: 'ascii' codec can't decode byte 0x84 in position 0: ordinal
not in range(128)
>>>
Hm, why does the 'encode' call complain about decoding?
Why do string objects have an encode method, and why do unicode objects
have a decode method, and what does this error message want to tell me:
>>> u"ä".decode("latin-1")
Traceback (most recent call last):
File "<stdin>", line 1, in ?
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe4' in position 0:
ordinal not in range(128)
>>>
