You don't have to guess that Macs normally use a different encoding because
it's stated explicitly in the fontname and fontinst documentation.

Can you explain what the switch is, and what you need to do to change it?
Does fontinst ever change this switch on its own?

Right - thanks for this.  Noted.

Is this mapping the `m' weight (fontinst name) to `mb' (fd file weight)?

Right - I think I've got this straight now.  Thanks.


Thanks :-)
