[gentoo-server] Special characters in the console

[Paulo Roberto Candido dos Santos]

Hello. I'm having trouble with special characters like cedilla (ç) and others like ã and õ. I have a Gentoo server here that runs a custom enterprise software based in ncurses and slang. I'm from Brazil and these characters are common in this country.

How can I enable these characters without using unicode? Yes... because of some misterious reason I can't use unicode.
