I am using pandoc to convert markdown files containing TeX bits to html.

Because the text is in Italian, I want to use comma as a decimal separator. However, pandoc keeps adding a space after the comma. Here is a simple example:

echo '0,5 $0,5$' | pandoc

it gives:

<p>0,5 <span class="math inline">0, 5</span></p>

Notice the space is not added when the number is not in math mode.

What I want is something similar to what is achieved by LaTeX package icomma, or some other workaround to prevent the insertion of the space. Any advice?

TeX math mode does not treat a comma like an ordinary character, but you can circumvent that by putting the comma in {}. However, that only works if you use MathJax for rendering:

echo 0,5 vs. $0,5$ vs. $0{,}5$ | pandoc --mathjax -s

outputs an HTML document equivalent to the following snippet:

<script src="https://cdn.jsdelivr/npm/mathjax@3/es5/tex-chtml-full.js" type="text/javascript"></script>
<p>0,5 vs. <span class="math inline">\(0,5\)</span> vs. <span
class="math inline">\(0{,}5\)</span></p>
