# through U=009F. Those Unicode values are reserved for the C1 Control character
# group, not printable glyphs. I don't know if the font files hold incorrect
# Unicode values, or this program is in error. See PDF::Builder::Resource::

# from Unicode to the various pages and 00..FF within each page is not clear at
