There have been two alternative suggestions from members of this list (thanks, you know who you are!).

Isn't it amazing that Windows XP was released quite a bit after Mac OS 
9, and the HooHah should be that it is not completely Unicode compliant.

The Arial set of fonts are, supposedly, OK as to Roman + Extended.

I am currently developing a set of programs (part of the "Richmond 
'does' dead languages" project) that lever Unicode; in each case I am 
going to bundle a FREE (as in all sorts of interpretations to what 
'Free' means) Unicode font that has the Unicode symbols my program levers.

That is certainly one way round things; just as long as the end-user is 
not so goofy that even with my instructions for Mac, Win and Linuc they 
cannot work out how to install a font.

I am loth to use the HTML one because my source text isn't HTML, so I would have to put all the paragraph markers, colour changes etc in by hand (I suppose), or get the original author of the text to do it (I predict a blank refusal), so I'm hoping MacToISO will be sufficient, and it probably will.

I do have a feeling that there is a possibility that all the Maths 
symbols you need are included in the extended ASCII set (1 - 256).
