\description{
  \code{charset_to_Unicode} is a matrix of Unicode points with columns
  for the common 8-bit encodings.

  \code{Adobe_glyphs} is a dataframe which gives Adobe glyph names for
  Unicode points. It has two character columns, \code{"adobe"} and
  \code{"unicode"} (a 4-digit hex representation).

\details{
  \code{charset_to_Unicode} is an integer matrix of class
  \code{c("\link{noquote}", "\link{hexmode}")} so prints in hexadecimal.
  The mappings are those used by \code{libiconv}: there are differences
  in the way quotes and minus/hyphen are mapped between sources (and the
  postscript encoding files use a different mapping).

  \code{Adobe_glyphs} include all the Adobe glyph names which correspond to
  single Unicode characters.  It is sorted by Unicode point and within a
  point alphabetically on the glyph(there can be more than one name for
  a Unicode point).  The data are in the file
  \file{R\_HOME/share/encodings/Adobe\_glyphlist}.
