About special vDOS fonts and other font stuff



Hello,

I was recently asked to make a special vDOS font by a Persian vDos user.
The task proved to be a daunting one, and I learnt some new tricks
trying to accomplish it. Without going into all the gory details,
basically, the thing was done by copying glyphs from Unicode positions
to the 8-bit ASCII range when code page 437 is active in the font editor
(I used Fontlab Type Tool). It is a lot of work as Arabic characters are
scattered around several Unicode sub-ranges, and you have to pick the
right variants from a host of possibilities that look almost the same to
Western eyes (there are initial, medial, final and isolated variants of
most of the letters). I found this resource indispensable when trying to
locate the characters: https://www.compart.com/en/unicode/. You just
enter the unicode name and you get a list of all the variants. Just
great, and highly recommended!


Some other Unicode resources for your enjoyment:
http://www.unicode.org/charts/index.html (official Unicode charts)
http://www.babelstone.co.uk/Unicode/babelmap.html (Unicode plane viewer)
http://www.shapecatcher.com/ (draw a character and find out which chr.
it is)
https://unicodelookup.com/ (good tool for finding Unicode chrs. when you
know part of the name, e.g. enter "alef" and you get Hebrew and Arabic
character names with alef in them)

http://www.alanwood.net/unicode/ (many exotic fonts)

I also stumbled upon THE OLDSCHOOL PC FONT RESOURCE
(https://int10h.org/oldschool-pc-fonts/readme/) which has many
interesting technical details about DOS fonts and a collection of bitmap
and TrueType fonts.
