Re: [ft-devel] Illegal cff font

[George Williams]

I received the following asking me to retract a comment I made. I will
provide the following clarification:

I received a pdf file from a user.
  This file claimed to be created by PDF-XChange
  This file contained an illegal type2 font.
   The font appeared to have been generating by subsetting a type1 font
   and converting it into type2 format leaving in seac, and calls to
   othersubrs routines.

I cannot verify that the file was indeed created by PDF-XChange, though
that seems likely. Nor can I verify that PDF-XChange produced the
incorrect font-subset.

Um, if you are writing text into pdf files then you are probably
including fonts, and probably subsetting them.
