Please refer to section 'Using Symbols' in the groff info file
which describes how groff glyph names are constructed.
Characters not encoded in the AFM file (i.e., entries which have -1
as the character code) are still available in groff; they get glyph
index values greater than 255 (or greater than the biggest character
code used in the AFM file in the unlikely case that it is greater than
255) in the groff font file.
Glyph indices of unencoded characters don't have a specific order;
it is best to access them with glyph names only.
