This is another very good suggestion. I will separate symbol and
accent search and I have already removed the accented characters from
the current version as that cluttered the whole thing too much.

I am working on a solution now and I think I have almost understood
what is needed. From what I have seen so far for a particular symbol I
need to know

and if it is made for math mode.

The last point is something I have problems with. How do I know which
symbols work in math mode and which don't? My understanding so far is
that there are some latex2e and ams symbols that work in both math an
text mode and the rest of the symbols is either math or text mode.
Math mode symbols are the ones from section 3 of the comprehensive
symbols list and all the others are text mode.
What bothers me most is that non math mode symbols will get rendered
without an error in math mode but the outcome is not as desired (so I
can't find out programmatically).

is a first idea to organize the symbols so that I can generate all the
graphics with a script. That also allows me to add necessary
information to recognized symbols such as the package needed. Am I
missing something important?
