Bug with mediawiki to plain text conversion

[gengiskhan600]

Hi

I don't know if this is a bug but when trying to convert a wiki page to plain text, https://en.wikipedia.org/wiki/Special:Export/Hokkaido, I've got empty results for :
{{convert|1,748|PD/km2|abbr=on}}
and partial result for
{{Nihongo|lead=yes|'''Hokkaido'''|北海道|Hokkaidō|{{IPA|ja|hok.kaꜜi.doː|pron|Ja-hokkaido.ogg}}

echo "{{convert|1,748|PD/km2|abbr=on}}" | pandoc -f mediawiki -t plain : no result

echo "{{Nihongo|lead=yes|'''Hokkaido'''|北海道|Hokkaidō|{{IPA|ja|hok.kaꜜi.doː|pron|Ja-hokkaido.ogg}}" | pandoc -f mediawiki -t plain : return {{Nihongo|lead=yes|Hokkaido|北海道|Hokkaidō|

Pandoc pandoc 3.1.11.1 on Ubuntu 25.04 (sorry if this is fixed in a newer version)

Thank you

That's a mediawiki template. Those are not currently supported.
