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.

This is tracked at Character disappears when printing an SVG and should be fixed with [pdf] Reduce drawing glyphs as paths which is in Chrome 130.0.6697.0 and later. After Puppeteer gains support for Chrome 130 and then rolled into decktape (something like 05eb620) then this should be fixed.

@bungeman thanks, that's very useful. I'll make sure we upgrade to Chrome 130 once it's supported by Puppeteer.
