Updating older versions of Adobe fonts? Slightly off-topic, but related in a way!

[Robert Lauriston]

I had a confusing problem with the three Zapf bullets my inherited
templates use for nested lists not rendering.

Eventually I figured out that the Type 1 font had never been installed
on my computer because the master font directory was missing the .pfb
file.

I didn't really want to install such an old font so I tried font
replacement of Zapfdingbat with ZapfDingbats BT, that didn't work
because the character set is not the same.

Eventually I decided to use Arial Black's Unicode characters 2022,
25E6, and 25AA instead.

Why Adobe mapped Zapf to Adobe Pi Std in the first place ...
