So the problem is that s.islower() might in some circumstances not equal
Is this really a bigger deal than the fact that in some circumstances
comparisons between 8-bit strings and Unicode strings will cause an
exception, depending on the contents of the 8-bit string. Or that sorts
could throw exceptions? Or concatenations can fail?
The only arguments I have heard for the need for the builtin function
"unichr" are based on the danger of concatenation failures in the
127-255 range. The price of this consistency is very high IMO!
