postscript adobeglyphnames

This setting is only relevant to PostScript output with UTF-8 encoding. It controls the names used to describe characters with Unicode entry points higher than 0x00FF. That is, all characters outside of the Latin1 set. In general unicode characters do not have a unique name; they have only a unicode identification code. However, Adobe have a recommended scheme for assigning names to certain ranges of characters (extended Latin, Greek, etc). Some fonts use this scheme, others do not. By default, gnuplot will use the Adobe glyph names. E.g. the lower case Greek letter alpha will be called /alpha. If you specific noadobeglyphnames then instead gnuplot will use /uni03B1 to describe this character. If you get this setting wrong, the character may not be found even if it is present in the font. It is probably always correct to use the default for Adobe fonts, but for other fonts you may have to try both settings. See also fontfile.
