[XeTeX] seac/endchar in type2 (OT CFF) fonts

[Pablo Rodríguez]

When I try to generate a rather big PDF file with the original GFS Didot
font, I get an error and the end of the process.

** WARNING ** "seac" character deprecated in Type 2 charstring.
** ERROR ** Type2 Charstring Parser: Parsing charstring failed:
(status=-1, stack=5)
Output file removed.

The problem is that the GFS fonts use the endchar operator for
generating the composite characters.

The issue is that the endchar command for OpenType fonts is deprecated
and because of that it isn't implemented in (x)dvipdfmx.

Since the endchar operator for composite characters in OpenType CFF
fonts could to be very similar to the seac operator in Type1 fonts, it
could be easy to implement it. I don't code, but there may be an
explanation of the seac/endchar for Type2 fonts at

I hope it helps,
