I read through your code. If I understand it correctly, you keep all the 
valid ASCII characters, and treat all non-ASCII characters "as valid".

This is pretty much the same thing as I did. The only difference is that 
I blacklist invalid ASCII characters and you whitelist valid ASCII 
characters. But we both "validate" all the non-ASCII characters.

But I think your code seems better than mine because it updates and 
reuses some common code. So I think I can abondon my patch and the 
unfinished test case.
