[ft-devel] Open Type font that contains Adobe CFF (PostScript outlines) data

[Vitaly Pasternak]

Hi All
I've just found an OpenType that freetype (current build) unable to open.
This font extracted from PDF 1.6 file. Font was embedded in PDF
document as subset in the FontFile3 stream and based on Type1 font.
PDFReference 1.6 describe OpenType embedding in the FontFile3 stream
in the 3 way

(PDF 1.6) OpenType font program, as described in the OpenType
FontOpenType font program, as described in the OpenType Font

Specification (see the Bibliography). OpenType is an extension of True-
Type that allows inclusion of font programs that use the Compact Font
Format (CFF).

This entry can appear in the font descriptor for the following types of font
dictionaries:

A Type1 font dictionary or CIDFontType0 CIDFont dictionary, if the
embedded font program contains a "CFF" table without CIDFont
operators.A Type1 font dictionary or CIDFontType0 CIDFont dictionary,
if the embedded font program contains a "CFF" table without CIDFont

So we have OpenType with Type1 font dictionary and CFF table - no HEAD
no META no SING tag... and FreeType return Error 2 - Unknown font
format.  Is it possible to fix the freetype for working with this king
of OpenType fonts
