Text copied from PDF is sometimes incorrect

Describe the bug When text in PDF contains string fi the resulting document is bit broken - when text is copied, it is not matching text visible in PDF. I suspect this is because fi is ligature? It happens with different fonts, but not with those which are built-in.

Expected behavior Copied text matches PDF document

If someone else is using google fonts I also managed to fix the fonts using fontforge with the following command

fontforge -lang=ff -c 'Open($1); Generate($2); Close();' xxx.ttf yyy.ttf

In my case suspect is font file.

After downloading font from another source and import in OpenSource BirdFont free software and export and use in my website.

It’s working as expected. Hope it helps someone 😃
