.Pp

The character set used for the markdown output is ASCII.

Non-ASCII characters are encoded as HTML entities.

Since that is not possible in literal font contexts, because these

are rendered as code spans and code blocks in the markdown output,

non-ASCII characters are transliterated to ASCII approximations in

these contexts.

.Pp

Markdown is a very weak markup language, so all semantic markup is

lost, and even part of the presentational markup may be lost.

Do not use this as an intermediate step in converting to HTML;
