Is it possible to use greek letters in the acronym package from latex in Quarto ?

Description

Hello,

I am facing the problem of not having the greek letters appear in the acronyms from using the acronym latex package in Quarto for pdf output.

I have written about this problem here and it seems the issue is not reproducible with pure latex code, hence it seems Quarto is doing something to the acronym package.

Here is my Quarto code.

mainfont: "Times New Roman"

# Acronyms


\begin{acronym}
  \acro{ifng}[IFN-$\mupgamma$]{interferon gamma}
  \acro{tnfa}[TNF-$\mupalpha$]{tumor necrosis factor alpha}
  \acro{nfkb}[NF-κB]{nuclear factor-kappa B}
\end{acronym}

# Regular text

- \ac{tnfa}
- \ac{ifng}
- \ac{nfkb}

I want TNF-α and not \ac{tnfa} ; IFN-γ and not \ac{ifng}.
When I use unicode characters in acronym such as \ac{nfkb}, it doesn't display in the acronym but in the regular text only.

It seems to come from scrartcl documentclass. Quarto uses Koma Script by default (https://quarto.org/docs/output-formats/pdf-basics.html#document-class). If you use article I think you won't see the issue.

documentclass: article

the issue is not reproducible with pure latex cod

What is the documentclass you set in LaTeX ? If you try with \documentclass[letterpaper]{scrartcl}, I believe you could reproduce the issue.

So something in Koma Script does conflict with acronym. Does not seem to be a quarto issue.

Using \documentclass[letterpaper]{scrartcl} with \setmainfont{Times New Roman} I end up with an undefined control sequence (using acronym). It works if I remove any mention of the acronym package. Everything seems to work once I use the libertine font somehow.

I do use scrreprt as the document class to use listof=totoc as a document option, making use of the default documentclass. It doesn't seem to work either if I use the article class.

For the record here is the code I used. I only changed the document class.

\documentclass{article}
\usepackage{acronym}
\setmainfont{Times New Roman}

\begin{document}
\begin{acronym}
  \acro{ifng}[IFN-γ]{interferon gamma}
  \acro{tnfa}[TNF-α]{tumor necrosis factor alpha}
\end{acronym}

\ac{tnfa}
\ac{ifng}
\end{document}

What I meant is that this does seem to work for me by adding documentclass: article

Does it work for you ?

Oh I misread, I apologize. Yes, this seems to resolve the issue! Thank you very much.
