 * Without embeded fonts, is PDF limited to only 4281 characters (of AGL)? How to display more glyphs?
 * </a>
 * <p>
 * This test constructs a type 1 font without embedded font program
 * that uses a non AGL name in its encoding's Differences array to
 * provide a glyph not to be found on the AGL. This is a counterexample
 * to the OP's original question.
