Emojis are missing from bold text and headings in PDF

[Graumagier]

When converting some reveal.js slides to PDF decktape is not including some emoji in headings as well as in bold text. I go from Markdown to Quarto (reveal.js) to decktape with decktape -s 1422x1067.

• HTML in Chrome:

• Final PDF output:

I've attached some minimal examples (HTML generated by Quarto and final PDF out of decktape).

I've also found When exporting to screenshots, emojis are missing in titles #209 which might be related, although there the issue only seems to occur in (image) screenshots.

Thanks!

Would be great if this could be fixed; also happening here - if you need additional information, just reply.

Avoiding bold emojis e.g. is an easy workaround.
