Translate

input to the

"John Gruber's 2004 specification" .

The output also almost conforms to the

.Lk http://commonmark.org/ CommonMark

specification.

.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;

instead, use

.Fl T Cm html

directly.

Documents causing warnings may render poorly when using other

.It Cm style

An input file uses dubious or discouraged style.

This is not a complaint about the syntax, and probably neither

formatting nor portability are in danger.

While great care is taken to avoid false positives on the higher

message levels, the

.Cm style

level tries to reduce the probability that issues go unnoticed,

so it may occasionally issue bogus suggestions.

Please use your good judgement to decide whether any particular

.Cm style

suggestion really justifies a change to the input file.

.It Cm base

A convertion used in the base system of a specific operating system

is not adhered to.

These are not markup mistakes, and neither the quality of formatting

nor portability are in danger.
