Michael Kubecka <misha@crl.com> kindly translated my Voynich fonts
into the True Type format that can be used in Macintosh computers.
He also wrote the following instructions for installation.

============================================================================
Macintosh Font Installation:

   Fonts for the Macintosh can have as many as two components: the
bitmap font (which is contained in a document whose icon looks like a
suit-case) and the postscript font (whose icon looks like anything
_but_ a suitcase) -- which is the postscript version of the bitmap. 
The bitmap component is required; the postscript component is optional
(but must always be accompanied by its bitmap version).  However, with
the postscript component, the font will look much nicer when printed.

   Installation of these fonts on the Macintosh is really very simple. 
Chances are, you're using some incarnation of System 7.  Basically, you
drag and drop any fonts (Bitmap suitcases or Postscript fonts) on top
of the icon of your System folder (which is usually at the root-level
of your Mac's hard drive).  If you're using System 7, your Macintosh
will say, "These belong in _______, should I put them there?" just
click OK and you're done.

   If you're using System 7.0, the Mac will copy the bitmap resources
directly into the System file and copy the postscript fonts into the
Extensions folder (or loose in the System folder -- I forget which). 
If you're using version 7.1 or greater of the operating system, the Mac
will put any font files in the Fonts folder and be done with it.

   The Extensions folder and Fonts folder are both at the root-level of
the System folder.

   The new fonts you added will not be available to any currently
running apps -- you'll have to quit them and re-launch them to get them
to re-acquire the system-wide font list.  In some versions of the OS,
the Mac will not allow you to make font changes (additions/deletions)
without quitting out of currently running apps -- in that case, it'll
notify you as such first.
 
   If you're using System 6 (which you probably aren't), you'll need to
use the Font/DA Mover utility to copy the bitmap fonts into the System
file.  (Consult your Macintosh manual).  You can drag and drop any
postscript fonts to the System folder, where they'll fall loosely into
the root level, which is fine.
