Glad you liked it

That would be great!

Here is what I have managed to work out. Apologies for answering in
org syntax :)

*** Second update [2007-11-03 Sat]
**** Finding LaTeX definitions for obscure symbols
     Look in the
[[http://www.ctan.org/tex-archive/info/symbols/comprehensive/][Comprehensive
LaTeX Symbol List]] to find the package
     where each symbol is defined.
     + =\usepackage{amssymb}= provides lots of the more obscure math
       symbols, such as ⋓ (=\Cup=).
**** Telling =ucs.sty= about symbols it doesn't understand
     We can use something like
:\DeclareUnicodeCharacter{977}{\ensuremath{\vartheta}}
     + Note that the code (e.g., 977) can be found from the TeX error
       message. It seems to be decimal, but I still haven't worked out
       its relation to the Unicode hex code.
     + A better way might be to add the new definitions to the ucs
       config files and run =makeunidef.pl=
------------------------------------------------------------------------

Attached are example .tex and .pdf that work for me.

Cheers

Will
