Hi Stuart,
Maybe anyone else can tell something more, but just some thoughts:

Gschem load a character definition file for each character it needs to
print on screen. The character definition file is a symbol containing
the letter to be printed. There's a symbol for each letter gschem knows
about, and they are in /usr/share/gEDA/sym/font, IIRC, (or /usr/local,
or whatever you installed gschem).
If gschem needs to print a string, then it loads an places one symbol
for each letter.

I think that function is only called when gschem needs to print
something on screen... do you need to do that in gattrib?

Is w_current->font_directory pointing to the directory where gschem font
symbols are stored (/usr/share/gEDA/sym/font, IIRC) ?

It's looking for the symbol of the letter you want to print on screen.
If it doesn't find it, then it tries to substitute it by the '?' symbol,
which should be found anytime, and if it doesn't find it, then raises
the error you are having (wrong variables).
Just take care that o_current->font_directory points to the right place
and I think it should work.

Carlos
