--------------------------------------------------------------
Looking at the commits from PDFBOX-2247, the use of FirstChar is not correct.
FirstChar should not be involved in encoding, it should be used only for
retrieving glyph widths from the Widths array. The"charOffset" variable isn't
needed, and the "code" variable in getCharacter() should be left un-tweaked.
It looks like PDType1CFont#getFontWidth() isn't using the Widths array at all,
which might be the cause of some problems? Or there may be deeper encoding
issues with 1.8, the original issue was PDFBOX-2058. None of this applies to
the trunk anymore.
