When I purchase commercial fonts or I obtain quality free fonts, I find many glpyhs listed in the PDF-documentation, typically at the end, listed as un-encoded glyphs aka un-mapped.
While any "normal" glyphs are listed with their code points, for example U+00C0, these unencoded ones carry some less structured references. I found for example:
If you have fonts without documentation and if you use Fontmatrix to look into, using the "Glypen" tab with the "Un-mapped Glyphs" block selected, you can find many amazing goodies. (Look at Comic Sans if you want an example.)
Now, how can I please access those glyphs for use in Scribus (and why not in other OpenSource tools like Inkscape)? If there is no direct way, I am happy to download some extra tool and do some copy and paste.
Sadly I am unable to get Adobe InDesign at the moment for several reasons, so answers like "just get expensive tools" might be helpful to other users, but not to me. Thank you.
