[Tex/LaTex] How to insert a keyword with accents (extendedchars) in listings

listings

This is what I would like to do:

morekeywords={SENÃO, ENTÃO, FAÇA, ATÉ, ENQUANTO, PARA, SE, DECLARA, DECLARE, E, OU, FIM_ENQUANTO, FIM_PARA}

I'm defining a new language, and I would like to use natural language words as keywords.

The problem is with keywords: SENÃO, ENTÃO, FAÇA, ATÉ.

I have solved the first problem, in showing special chars with:
How to insert code with accents with listings?

The alsoletter here, doesn't work for me, I got an error when using it: alsoletter={Ç,É,Ã}.

I managed to "solve" this by replicating the keywordstyle within the literate set. There is probably a better way to do it, but this works well for a few keywords.

\documentclass{article}

\usepackage[brazilian]{babel}
\usepackage[utf8]{inputenc}
\usepackage{color}
\usepackage{listings}

\newcommand\keywordstyle[1]{{\color{red}\bfseries{#1}}}%

\lstset{%
literate=
        {Ç}{{\c{C}}}1
        {Ã}{{\~{A}}}1
        {á}{{\'{a}}}1
        {ENTÃO}{{\keywordstyle{ENT\~{A}O}}}5
        {SENÃO}{{\keywordstyle{SEN\~{A}O}}}5
        {FAÇA}{{\keywordstyle{FA\c{C}A}}}4
}

\lstdefinelanguage{pseudo}
{
extendedchars=true,
alsoletter={_},
morekeywords={ENQUANTO,PARA,SE,DECLARA,DECLARE,E,OU,FIM_ENQUANTO,FIM_PARA},
ndkeywords={NUMERO,TEXTO,LEIA,ESCREVA},
sensitive=true,
morecomment=[l]{//},
morecomment=[s]{/*}{*/},
morestring=[b]"
}
