- \brief 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:
- <table>
- <tr> <th>Char</th><th>Codepoint</th><th>Name</th>  <th>Char</th><th>Codepoint</th><th>Name</th> <th>Char</th><th>Codepoint</th><th>Name</th></tr>
- <tr><td>ƒ</td><td>U+0192</td><td>florin</td><td>‚</td><td>U+201A</td><td>quotesinglbase</td><td>™</td><td>U+2122</td><td>trademark</td></tr>

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