Font of menu on the Mac?

[Ken Corey]

Hi All,

I have an oddball problem.

I'm using a custom font to display cursive english writing.  This uses 
unicode characters, and non-standard glyphs (e.g. the left square 
bracket character U005B is a character to join between letters, not a 
bracket).

I would like to write a little tool to let me easily compare joins 
between letters.

I thought of three letters in a label like this:
   left-letter join-letter right-letter

To control this just needs 3 option menus, which when selected updates 
the label...

So I set the option buttons, and with the help of this brilliantly 
written article:

Have the correct letters showing in my option buttons (mostly).

However, on the Mac, when I do a pull down, it reverts to the system 
font, which shows "incorrect" characters (for my purposes).

Is there a way to control the font of menus on the Mac?
