A glyph is simply a character image. It doesn't necessarily
correspond to a character code though.glyph images can be
rendered for all character pixel sizes.A face object
contains one or more tables, called charmaps, that are used
to convert character codes to glyph indices.Note also that a
given charmap might not map to all the glyphs present in the
font.
