These character vectors provide the PostScript language code use for selecting a new font in the output produced by the PostScript printer driver. The default value for the setfont option to ps.options is a copy of the ps.setfont.std dataset.
The primary use of changing the setfont option is to select a different font "encoding vector". The ps.setfont.latin1 dataset can be used to cause each font to be reencoded using the ISOLatin1Encoding PostScript vector. This changes the font to use the ISO Latin-1 (ISO 8859-1, ECMA-94) character set.
