| \description{ |
| \code{charset_to_Unicode} is a matrix of Unicode code points with |
| columns for the common 8-bit encodings. |
| |
| \code{Adobe_glyphs} is a data frame which gives Adobe glyph names for |
| Unicode code points. It has two character columns, \code{"adobe"} and |
| \code{"unicode"} (a 4-digit hex representation). |
| } |
| \usage{ |
| charset_to_Unicode |
| |
| Adobe_glyphs |
| } |
| \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} includes all the Adobe glyph names which correspond |
| to single Unicode characters. It is sorted by Unicode code point and |
| within a point alphabetically on the glyph (there can be more than one |
| name for a Unicode code point). The data are in the file |
| \file{\var{\link{R_HOME}}/share/encodings/Adobe_glyphlist}. |
