UnicodeDecodeError in Python version when using Cyrillic characters. about google-diff-match-patch HOT 1 CLOSED

Thank you Alexandr for the bug report and the patches.  Sorry for the delay.  I 
have
fixed the Unicode issues in diff_fromDelta and patch_fromText.  In both cases I 
added:
    if type(text) == unicode:
      text = text.encode("ascii")
These are two functions which are expecting a subset of ASCII characters.

However, your patch also made changes to diff_text1, diff_text2, patch_apply
and patch_obj.__str__.  Despite many tests, I am unable to find scenarios where
the existing code fails when passed Unicode.  An example testcase would be most
apreciated.

In the mean time, I've pushed out a new version which includes the Unicode 
fixes for
diff_fromDelta and patch_fromText in the Python version, as well as a new unit 
test
in all three versions which verifies the behaviour of invalid Unicode sequences 
(e.g.
%c3%xy).
