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}.

test.tex

\documentclass{article}

\usepackage[brazilian]{babel}
\usepackage[T1]{fontenc} 
\usepackage[utf8]{inputenc}
\usepackage{listingsutf8}

\usepackage{listings}

\lstset{%
        inputencoding=utf8,
        extendedchars=true,

  • Remark - you're supposed to not include the comma in alsoletter specification -- but the reaon why it error out is lst@SelectStdCharTable does not include the definitions for those characters, basically listings just have poor utf8 support -- I guess it's possible to somehow hack all the characters in 128-255 to be "letter", but using the literate hack seems to be the best option here. – user202729 Aug 01 '22 at 14:37

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]"
}

\begin{document}
\lstinputlisting[language=pseudo]{foo.pseudo}
\end{document}

For Hungarian documents, the following settings work with TeX Live 2013 and PDFLaTeX. With XeLaTeX, you should escape the ő/Ő and ű/Ű characters with the escapeinside option.

\documentclass{report}

\usepackage[magyar]{babel}
\usepackage{ifxetex}
\ifxetex
  \usepackage{fontspec}
\else
  \usepackage[T1]{fontenc}
  \usepackage[utf8]{inputenc}
  \usepackage{lmodern}
\fi
\usepackage{listings}

\lstset{
    basicstyle=\ttfamily,
    keepspaces=true,
    escapeinside={(*@}{@*)}, % only required for XeLaTeX
    columns=flexible, % only use with keepspaces=true       
    literate=*
        {á}{{\'a}}1
        {é}{{\'e}}1
        {í}{{\'i}}1
        {ó}{{\'o}}1
        {ö}{{\"o}}1
        {ő}{{\H{o}}}1
        {ú}{{\'u}}1
        {ü}{{\"u}}1
        {ű}{{\H{u}}}1
        {Á}{{\'A}}1
        {É}{{\'E}}1
        {Í}{{\'I}}1
        {Ó}{{\'O}}1
        {Ö}{{\"O}}1
        {Ő}{{\H{O}}}1
        {Ú}{{\'U}}1
        {Ü}{{\"U}}1
        {Ű}{{\H{U}}}1
}

\begin{document}

% for PDFLaTeX
\begin{lstlisting}
árvíztűrő tükörfúrógép á é í ó ö ő ú ü ű
ÁRVÍZTŰRŐ TÜKÖRFÚRÓGÉP Á É Í Ó Ö Ő Ú Ü Ű
\end{lstlisting}

% for XeLaTeX
\begin{lstlisting}
árvízt(*@ű@*)r(*@ő@*) tükörfúrógép á é í ó ö (*@ő@*) ú ü (*@ű@*)
ÁRVÍZT(*@Ű@*)R(*@Ő@*) TÜKÖRFÚRÓGÉP Á É Í Ó Ö (*@Ő@*) Ú Ü (*@Ű@*)
\end{lstlisting}

\end{document}

Note that without keepspaces=true, the columns=flexible option will cause (some) space characters before the accented characters to disappear.
