Fonts not embedded in PDF

Hi, i was using weasyprint 52.2 with python 3.8 on fedora32. After upgrading to fedora33, my fonts are not embedded into the resulting pdf any more. fedora33 uses python 3.9, i also upgraded to weasyprint 52.4… no change to the result.

What i did so far:

1. using weasyprint standalone (this is my main usage)

weasyprint in.html out.pdf

A pdf is generated, embedded fonts missing

1. using weasyprint as python script

from weasyprint import HTML, CSS
from weasyprint.fonts import FontConfiguration
font_config = FontConfiguration()
html=HTML('in.md.html')
html.write_pdf('out.pdf',font_config=font_config)

same result, no fonts in pdf

My Html uses an external css with @font-face e.g.

@font-face {
  font-family: mySerif;
    font-weight: normal;
    font-style: normal;
    font-stretch: normal;
  src: local('Liberation Serif'),
       url(file:///usr/share/fonts/liberation-serif/LiberationSerif-Regular.ttf) format('truetype');
}

The browser has no problems rendering my embedded fonts, neither did weasyprint on fedora32/py3.8 (if that matters at all…) So, my old working pdf output had these fonts (successfully embedded)

name                                 type              encoding         emb sub uni object ID

IQFZUN+RobotoMono-Regular            TrueType          WinAnsi          yes yes yes    113  0

The new one has only these default fonts:

name                                 type              encoding         emb sub uni object ID

YNMLOL+BitstreamVeraSans-Bold        TrueType          WinAnsi          yes yes yes     84  0
EZEEOY+BitstreamVeraSans-Oblique     TrueType          WinAnsi          yes yes yes    122  0

I had a (one!) font embedded into my pdf when using

weasyprint -v ${filename}.md.html ${filename}.md.pdf -s <(echo 'body { font-family: 'Liberation Serif' !important }')

with this font list:

name                                 type              encoding         emb sub uni object ID

EZEEOY+BitstreamVeraSans-Oblique     TrueType          WinAnsi          yes yes yes    115  0

Overriding with user styelsheets and !important cannot be the solution… I’m running out of ideas for now, any help?

@liZe Thanks for bringing this to my attention. I recently got an automated notification that WeasyPrint’s test suite has even more test failures in Fedora but I did not have time to debug this.
