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? Werner
