They're there now in the new fontcap file.

I added a structure to hold the information in the fontcap file to 
general/g.mkfontcap/local_proto.h - perhaps it should go somewhere more 
general to be shared with d.font. Currently it is:

struct GFONT_CAP
{
     char *name;     /**< Short name for this font face */
     char *longname; /**< Descriptive name for the font face */
     char *path;     /**< Full path to the file containing this font face */
     int index;      /**< Index within the file of this font face */
     int type;       /**< Type of this font face (currently stroke or freeype) */
     char *encoding; /**< Encoding to be used with this font face. */
};

#define GFONT_STROKE 0
#define GFONT_FREETYPE 1

Yes. I suppose the GUI will need it to produce pretty output (long names) 
and populate the encoding text box with a default value etc.
