According to FF's doc, this number is "the encoding of the glyph in the
current font expressed in decimal". I'm not sure what it means, but it's
not the glyph index. To get what FF thinks is the glyph index, use :
Print(GlyphInfo("GlyphIndex")) # printed on stdout
That's what my program uses, and it gives correct results.

GlyphInfo("GlyphIndex") agrees with ftgrid.
So I believe my program is reliable.
