[Tutor] help: UnicodeError: ASCII decoding error: ordinal not in range(1 28)

[Walter Vannini]

Hi Grzegorz,

I don't know unicode well enough to answer your question.
I hope someone out there might be able to tell you (and me) what's going on.

I can tell you that the error can be reproduced very easily via:

>>> str(u"\x81")
which attempts to convert the unicode object u"\x81" to a string object

or via:

>>> unicode("\x81")
which attempts to convert the string object "\x81" to a unicode object
