Detailed Description

PostScript graphical backend.

PostScript text uses vectorial fonts for the latin alphabet (exactly: all unicode characters between U+0020 and U+017F, that is, ASCII, Latin-1 Supplement and Latin Extended-A charts) plus a few other characters:

Char	Codepoint	Name	Char	Codepoint	Name	Char	Codepoint	Name

All other unicode characters are output as a bitmap.
FLTK standard fonts are output using PostScript standard fonts: Helvetica, Courier, Times (and their bold, oblique, italic variants).
