Here is the source for the definition:

#if 1
# define FONT_NAME "Arial"
#else
# define FONT_NAME "Helvetica"
#endif

Maybe this can be moved into libgeda as a configuration option. Perhaps
something like the following. I put the following configuration item into
system-gsch2pdf.

; font family-style
;
; Sets the font family and style to use for PDF creation. Size can be included,
; but will be ignored. The program uses the size specified in the schematic file.
;
(font "Sans")
;(font "Arial")
;(font "Arial Narrow")
;(font "Helvetica")

Would this option be useful?

Cheers,
