In 1996 I bought a copy of Fontographer, having previously developed
several bitmap fonts
for Macintosh with Fontastic (for Anglo-Saxon and Old Slavic). At that
time (1996) it was possible
to use Fontographer to make fonts with about 4000 characters which one
could access through Mac Keyboard layouts. As far as I know, although
Unicode development started in 1986, there was
no question of Unicode compatibility (and I had not heard of Unicode).
Presumably (?) ALL that Macintosh system 7.5 was doing when it
displayed characters outwith the ASCII set was what I need now?
Not necessarily - I believe system 7.5 was pretty advanced when it came
to text and fonts. In particular, I'm sure it had an implementation of
TrueType at least. The only difference then was that a font might have
multiple CMAP tables for different text encodings as the Unicode
encoding was still in its infancy. Even bitmap fonts (which might not
necessarily have been TrueType) would have to declare what encoding it
assumed was being used so that things could be mapped appropriately.
In actual fact, fonts don't really care about encoding exactly - they
provide tables which map indexes in an encoding to the glyphs to
represent them. Everything inside the font runs on glyph indexes and not
codepoints in any encoding. Indeed (as I mentioned in another email) you
can use the PUA area for your font as a direct codepoint->glyph map.
I'm glad you find it unusable: I have a G5 iMac (connects to the
Internet using TenFourFox) running
dual-boot 10.4 and 10.5 that is stuffed with lots of PPC software that
I bought when I had more money for that sort of thing than I have now:
I would be lost without the availability of Appleworks and
Bryce.
I'd point out that TenFourFox is a fork of FireFox and is not a Mozilla
project.
i.e. A third-party has taken the responsibility for maintaining a fork
of an open-source project to ensure there is a variant of FireFox which
runs on older systems...
Warmest Regards,
Mark.
