All About Python and Unicode

Wednesday, December 26. 2007

I got caught on a weird issue comparing two strings in Python:

CODE:

/home/misha/python/wav2mp3.py:45: UnicodeWarning: Unicode equal comparison failed
to convert both arguments to Unicode - interpreting them as being unequal
if candidate == outname.lower():

I took a while before I could figure out what the problem was, but only after having a more or less thorough read through this site.

Two weeks before I started writing this document, my knowledge of using Python and Unicode was about like this: All there is to using Unicode in Python is just passing your strings to unicode()...

The "weird issue" was that the LHS in my comparison was a UTF string, while the RHS was a UTF-8 encoded string. My lame print debugging statements did nothing to highlight the issue, as print was correctly interpreting both the encoded and un-encoded strings. The repr() method proved quite useful in this case.

Thanks for the comment. I'd repay the favour and comment on your site, but it requires me to register and I simply cannot be bothered. Good luck with it.
