Sorry. Should have sent out a note earlier. The file attached to that
first message had been inappropriately truncated; so the cff file was
bad.
I am now able to read cff files, but *only* when I have patched the
freetype sources (cffload.c, line 1608) to skip the check which requires
num_glyphs to be 229.
Attached are two cff files which I am able to read with the patched
sources. They were extracted from typical pdf documents. It would also
be a good idea to test that freetype can load the example file given in
the cff documentation. Below, I've appended the skeleton for such a
test.
