tl;dr: Python-PDFkit generates an error when a CSS file is provided during HTML to PDF conversion.
I'm using Python-PDFkit (that uses WkHTMLtoPDF based on Qt) to turn an HTML file into a PDF file. The HTML is generated by Jinja2 and contain base64 images, text and Bootstrap-like custom CSS file. The conversion is correct when no CSS file is provided :
import pdfkit
pdfkit.from_file(file_name + ".html", file_name + ".pdf", options=pdfkit_options)
But when I add CSS files :
css_files = ["boosted-4.2.2-dist/css/Helvetica.css","boosted-4.2.2-dist/css/Icons.css", "boosted-4.2.2-dist/css/boosted.css"]
pdfkit.from_file(file_name + ".html", file_name + ".pdf", options=pdfkit_options, css=css_files)
Then PDFkit produces a WkHTMLtoPDF error:
Traceback (most recent call last):

load glyph failed err=24 face=0x40727c0, glyph=3

What's wrong? Any idea? I'm working on a CentOS and Python 3 environment.
