OK, then, I’ll do it...and I did it...and it’s kind of sweet.  There are
some problems however:

1.  Not all symbols have a TeX equivant that I know about.  If anyone is
interested, please do go through the vector, looking for
\unknownchar’s and substitute in the appropriate TeX sequence.

2.  Many negated operators are traditionally written using \not.  The
Unicode transformations don’t work with sequences like these.  I
don’t know enough about the Unicode vector transformations to
assertain how to solve this problem.  Can someone perhaps tell me
how to solve this issue?

Thanks, and do enjoy the wonderful world of Unicode,
nikolai
