/CHARSET=charset_name

    The character set used in the input text. Many character
    sets are supported; see the complete list in the file PMDF_
    TABLE:CHARSETS.TXT. PMDF PS will construct an appropriate
    encoding vector to render the character set as well as possible
    in PostScript.

    Note that the selection of fonts can affect whether or not all
    characters can be correctly displayed. The Courier font works
    quite well; other fonts can lack some accented characters.
