Ideally, there should be a proper ToUnicode cmap in the PDF so that
copy and paste gives good results. On the PostScript side, it should
be theoretically possible to use the `GlyphNames2Unicode' dictionary
(an undocumented Adobe Distiller extension) so that PS->PDF software
can provide non-standard mappings. Right now, I haven't found a full
example code for that.
However, the gropdf driver could directly add support for that...
Deri?
