Hi Alfredo,
to put in some foreign characters in your text you can do it this way:

look up the character in the character table
       (N tilde = Alt 209, n tilde = Alt 241)

then declare it in your .pov file
       #declare Nt=chr(209);
       #declare nt=chr(241);

and use it in your text like this
       concat("Ni",nt,"o");

This sounds a little complicated, but it works.

Hope it helps,

greetings, em-sigma
