The ISO 8859-1 (latin1) character set may be used for international characters
in plain text, LaTeX, HTML, LyX, and RTF output (GNU info support for
ISO 8859-1 may be possible in the future). To use this feature, give the
formatting scripts the --charset=latin
flag, for example:
% sgml2txt --charset=latin foo.sgml
You also can use ISO 8859-1 characters in the SGML source, they will
automatically be translated to the proper escape codes for the corresponding
output format.
