I'm getting UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-51: ordinal not in range(128) exception trying to use string.maketrans in Python. I'm kinda discouraged with this kind of error in following code (gist):

I mean, why Python string.maketrans trying to use ascii table anyway? And how comes English alphabet letters are out of 0-128 range?
$ python -c "print ord(u'A')"
65
$ python -c "print ord(u'z')"
122
$ python -c "print ord(u\"'\")"
39
After several hours I feel like absolutely exhausted to solve this issue.
Can someone say what is happening and how to fix it?
maketranscannot handle non-ASCII characters. (But Python 3 should be fine.) – Cryptogrammaketransrequires you to map unicode characters to ordinals (I don't know why). – Backrestunidecodeis not an option for me (explained below in @thg345's answer), though it's handy to use. @kojiro, the code above works fine with python 3 just as you said. – Gaul
