   I  put  a  modified  unicode.tmac in a local directory. I
never will change these characters, they are  in  everywhere
and  in all kind of code. I like ASCII, and besides nowadays
isn't necessary for a spanish like me write ano  instead  of
año  (memories of my old spectrum...) I prefer use ASCII and
complete it only with my needs (accents, ¿, ¡,...).

   Thanks to all for the help.
