[🐛 Bug]: PDF generated on selenium nodes are missing some unicode characters [𝘽𝙍𝙐 U+1D63D]

[quertenmont]

What happened?

Hello,

I am generating some pdf on a selenium node containg unicode characters like these: 𝘽𝙍𝙐 (i.e. U+1D63D )
Unfortunately, the generated pdf doesn't show those characters but have a "no glyph box" instead.

I have no issue when I print the pdf from my chrome brower, so I suppose that the issue is related to a missing font in the docker, but I don't know which one neither how to add it.

Could someone please help and batch the docker ?

Thanks in advance,

I tried to search for something and saw this https://support.google.com/docs/thread/187910945/no-glyph-script-error?hl=en
So, this means a font needs to be installed in Node?

[VietND96]

I saw you mentioned print the PDF. However, above ticket also mentioned

NOTE: Although the characters/glyphs may be viewable on screen, they do not necessarily render when printing to PDF.

Also, can you provide what language is used in your PDF that has font issue?

@VietND96 thanks for looking into it.
It comes from lol LinkedIn post written in English actually, but some people use these special characters to have some effects (bold and/or italics) on the letters.
They typically use generators like these https://yaytext.com/bold-italic/ to convert there text and bypass font standardisation enforced by social platforms.
You can use the generator to make your tests and make sure you cover the full range of Unicode used.

Thanks in advance
