Dear FreeTypers,
is this an error? The CFF driver assumes that charstrings are Type 2, and
has no provision for other types. I believe this from the fact that
top->charstring_type is correctly set but never referred to.
However, the Compact Font Format Specification
(http://partners.adobe.com/asn/developer/pdfs/tn/5176.CFF.pdf) states that
"The format of the charstring data, and therefore the method of
interpretation, is specified by the CharstringType operator in
the Top DICT. The CharstringType operator has a default value
of 2 indicating the Type 2 charstring format which was designed
in conjunction with CFF. Type 1 charstrings are documented in
the Adobe Type 1 Font Format published by Addison-Wesley.
Type 2 charstrings are described in Adobe Technical Note #5177:
Type 2 Charstring Format. Other charstring types may also be
supported by this method."
I believe, therefore, that the CFF driver should be changed so that, at
least, it supports Type 1 charstring format.
Best regards,
Graham Asher
