Just as a general note, I wanted to point out that we do not want to output faked glyphs unconditionally, since the user might choose to work with a font that has those glyphs. If a font does not have the glyphs, we can indeed use .fchar/.fschar/.schar to substitute embedded Postscript code to manipulate things on the fly. Ideally, however, this should be fixed by providing a suitable font. Could we perhaps distribute a custom Type 3 (possibly Type 1) font that contains only these missing glyphs, accessed as fallback font using .special/.fspecial? > Does PostScript have an erasure operator? Postscript has a clipping operator, which inhibits drawing anything outside a given region.
