Title:
  font substitution fails if font name contains a dash

Status in “fontconfig” package in Ubuntu:
  New

Bug description:
  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.
  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 12.04 and 13.10 (x86_64)

  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...
