It seems X-locale 'C' supports codeset ISO8859 on your system, but 
you need ISO8859-1 (Latin-1).
There are several solutions of you problem.
1. You may set LANG=es_AR and LC_MESSAGES=C. You will have english operation
   system's messages, but 'native' another locale categories.
   man setlocale for more info.
2. You may create and install new locale using localedef command.
3. Try something like LANG=C.iso88591. This will give you C locale with
   Latin-1 codeset.
   Look for appropriate LANG in X locale database
   (/usr/X11R6/lib/X11/locale/locale.*) if LANG=C.iso88591 is not installed 
   on you computer.

I'm not familiar with Pronto: it may allow to select font manually
or do it automatically depending on content-type of a letter.
