Not reading the font on the PDF

Which product are you using?
PDF.js Express Viewer

PDF.js Express Version

Detailed description of issue
I have a problem with the font on Firefox browser, and on Chrome and Edge it shows an error for the font in the console, but still displays the font correctly. Can I replace the font on browsers that don’t read a certain font to display it with another font and display the text nicely on the PDF?"

Expected behaviour
To display the text nicely on the PDF, and not showing some characters.

Does your issue happen with every document, or just one?
With all documents that contain that font.

Fonts are a little tricky on the browser with PDFs, if the font isn’t embedded into the PDF we have to make a “best guess” as to what the font should be on the back end.

to add a custom font
