Similar expressions where the warning is raised or not (depending on "latin-1" comparison):


$ python2.7 -c "print u'd\xe9' in {'foo', 'd\xe9r'}"
False
$ python2.7 -c "print u'd\xe9' in {'foo', 'd\xe9'}"
-c:1: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
False


$ python2.7 -c "print 'd\xe9r' in {u'foo', u'd\xe9'}"
False
$ python2.7 -c "print 'd\xe9'  in {u'foo', u'd\xe9'}"
-c:1: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
False
