BTW, exactly what is a letter? :-)

I think I've seen some languages that accept pretty much anything in 
the 128..255 range (where å, ä, ö, é, ñ, ü and whatnot reside in many 
environments) as letters, but I have a bad feeling about it... If 
nothing else, it can make the code hard or impossible to read and 
edit on a machine with a different local than what the author was 
using.
