You may test it with Robert's WebEq, not thinking about embedding MML in
HTML.

WebEq some times disappoints me with smth like

but I hope it is fixed already in the new version.
Robert, do you need bug reports on version 2.2 ?

_VERY_  partial. You may try the attached file with Amaya.

I don't think so. I also have problems with those entities, but I think
MML should
accept _every_ UNICOD entity (e.g. Cyrillic). The problem I have is that
there is no
(is there?) complete UNICOD font with all 2^16 (actually  < 2^16)
characters.
Currently my reader skips entities which are not supported with our
font, but I think
the better way is to show nearest character (e.g. for DDotrahd use
RightArrow).

> Any volunteers to provide me with rendering engines to test the
output?
I spoke with my Boss, and, probably, I will make available
some short version of our program to test your output and to test my
reader/writer.
But it will not be earlier then in a week.
