New submission from Mark Summerfield:
I am using Python 3.4.3 on Xubuntu 14.04 LTS 64-bit.
I have a program that when run repeatedly sometimes what I expect, and
sometimes does not:
$ ~/tmp/normbug.py
OK ('The AEnid oevre', '==', 'The AEnid oevre')
$ ~/tmp/normbug.py
OK ('The AEnid oevre', '==', 'The AEnid oevre')
$ ~/tmp/normbug.py
OK ('The AEnid oevre', '==', 'The AEnid oevre')
$ ~/tmp/normbug.py
BUG ('The aenid oevre', '!=', 'The AEnid oevre')
$ ~/tmp/normbug.py
OK ('The AEnid oevre', '==', 'The AEnid oevre')
$ ~/tmp/normbug.py
OK ('The AEnid oevre', '==', 'The AEnid oevre')
$ ~/tmp/normbug.py
OK ('The AEnid oevre', '==', 'The AEnid oevre')
$ ~/tmp/normbug.py
OK ('The AEnid oevre', '==', 'The AEnid oevre')
$ ~/tmp/normbug.py
OK ('The AEnid oevre', '==', 'The AEnid oevre')
$ ~/tmp/normbug.py
BUG ('The aenid oevre', '!=', 'The AEnid oevre')
$ ~/tmp/normbug.py
BUG ('The aenid oevre', '!=', 'The AEnid oevre')
$ ~/tmp/normbug.py
OK ('The AEnid oevre', '==', 'The AEnid oevre')
As you can see, sometimes the left (actual) is case-folded, and sometimes it
isn't which is surprising given the code (which is attached).
Of course this could be a mistake on my part; maybe I've misunderstood how the
unicode normalizing works.
