  The stopCondition logic comes from some ancient time, and it simply
use a few values above 255 for internal purpose to indicate what to do
when "EndOfRun" or "CrossedX" happens.

  To display (Character value: 256) or a-macron (Character value:
257)...  I actually haven't made a font file for these range of
characters, but you should be able to load (for example) a TrueType
font with these glyphs.
