essentially arbitrary but they were used (in some cases including
hacking metafont parameters to make font variants) to make the
example png images for the 1Dxxx plane a alphanumeric blocks
that were in the mathml2 spec and now the entities spec.
But I'm not sure I even have those fonts any more, perhaps on an archive
tape somewhere...

Thanks, but first got to work out how best to do mstack and mlongdiv
which have been added to the spec since I last really stressed this.

Hmm I have cambria math (not sure if I can use it though for the
purposes I have in mind given its rather restrictive licence)
