A composite (Type 0) font with the 8/8 mapping picks a descendant font and a code in it with each pair of bytes (PLRM 3rd ed., 5.10). The reader set its strings as type in a font of the composite font's name, the bytes read as Latin-1 and at a thousand times the size, so EPS from pdftops of a PDF with embedded TrueType fonts showed nothing, or one black shape, where its type was. Characters now go to their descendants: a Type 42 font's glyphs are drawn from the TrueType outlines its sfnts strings carry (Adobe Technical Note 5012), by the glyph index CharStrings gives their names, spaced by their own widths or the show operator's numbers; charpath and stringwidth read them too. A Type 3 descendant runs its procedures, and a descendant found by name sets its character as type at the composite font's size.
