Thank you, Willi, I wasn't aware of this nice font module!
(btw, running it on ArialUnicode with 2 columns and 10pt produces 500 PDF pages and a peak memory usage of 1.2 GB!).

I like the idea of using glyph names rather than unicode numbers. For my actual purpose your suggestion works perfectly, with \fontchar{emptyset}. 

Beside this there are many glyphs with only "math names" (the rightmost column in the fnt-10 output). I couldn't make \fontchar work with these. For example the fore-mentioned char "2300 works with \fontchar{uni2300} but not with \fontchar{varnothing}.

Is there a way to set these chars by their math name?
