rtftohtml automatically recognizes and converts bold, italic and underlined text. If a certain range of text is written using a monospaced font such as Courier, it also automatically creates monospaced HTML-output for that range. What fonts are considered to be monospaced can be configured in the file html-trans in section .TMatch ("monospace fonts -> tt"). By default the fonts "Courier", "Courier New" and "Palatino" are expected to be monospaced.
If you get warning messages such as "no output translation for ..." when running rtftohtml you can either replace that character with a less exotic one in your RTF-file or add a translation to the end of rtftohtml's library file html-map, such as "character translation".
The newline
character (created by Shift-Return) will be automatically
converted to the
corresponding HTML-tag,
as will the unbreakable space (created by Control-Shift-Space).
