Warning: Missing charsets in String to FontSet conversion

[Manuel Cebrian]

I am running xemacs on kubuntu dapper drake with the default settings 
(just installed).

$ xemacs
Warning: Missing charsets in String to FontSet conversion

This message appears allways. There is a ?related? bug when I compile 
using xemacs M-x compile, there are some strange (incorrect) caracters 
in the compilation window (\200\230):

/home/mcebrian/docencia/ssoo/enunciados/p2/codigo/primos/
gcc -g -lm primes.c
primes.c:14:2: error: invalid preprocessing directive #defini
primes.c: In function ?\200\230main?\200\231:
primes.c:109: error: ?\200\230LEER?\200\231 undeclared (first use in 
this function)
primes.c:109: error: (Each undeclared identifier is reported only once
primes.c:109: error: for each function it appears in.)

Compilation exited abnormally with code 1 at Thu Oct 19 16:40:04

Could you help me solving this please?
