AttributeError: '_TTGlyphSet' object has no attribute 'values'

Hello,
First of all thanks for this library which is very useful for me.

I have a bug that appeared in 63.0, when I am using the write_pdf function with a render for fonts. I don't know if the bug is from the library or if the code itself is bad written from me

the code :

css = CSS(string=css_content, font_config=font_config, base_url=f'{path}/stylesheet.css')
HTML(string = html_content, base_url=f'{path}/index.html').render(font_config=font_config, stylesheets=[css]).write_pdf(f'{path}output.pdf', stylesheets=[css],font_config= font_config)

Here is the log (I removed the path each time) :

AttributeError: '_TTGlyphSet' object has no attribute 'values'

Thanks if you can help :)

Hi!

Thanks for the report, maybe there’s a bug in fonttools. Could you please share the font that’s causing this problem?
