Created attachment 94316 Example PDF wit such a font that is not embedded and gets not substituted properly
I have PDF that contain a font named Code-128, not embedded. Just installing this font does not help: it is not picked properly and evince uses DejaVu for rendering, which is bad for a barcode font! A fc-list does show the installed font. A fc-match does not work and always returns "DejaVu Sans" "Book"
Expected: fontconfig picks the installed font and uses it for rendering in evince. fc-match returns the font name it it matches, no matter what character is contained in the name.
Tested on Ubuntu 12.04 and 13.10 (x86_64) with fonconfig 2.10.93
Temprary workaround i currently use: I used fontforge to change the font by removing the dash in the font name. Then i implemented a substitution for Code-128 to be substituted by Code128.
Result: evince displayed the font properly but fc-match still does not work.
Unfortunately i have no influence on the PDF generation, they are generated by a German Ministry of Interior and i have been struggling for three years now to get them to create only PDF-A (fonts embedded), but they refuse to implement that without giving meaningful arguments. We, like many other companies are forced(!) to utilize these buggy PDFs, probably most companies use Windows+AdobeReader and don't have that problem...
