Re: [Texmacs-dev] is_iso_alpha function [MORE]

[skhilji]

More of my research on this.  It turns out that at least in Windows encoding:

159 is a Y with two dots on top of it
189 is the one-half sign
190 is the 3/4 sign
191 is the inverted question mark.

My again I don't know why these characters are treated separately?  Why not 
195---which stands for an A with a ~ on top of it.
