I've tried converting with pretty much all of them, mostly from a mediawiki excerpt, and none produced a perfect result. I've found strict markdown to be the closest, but it's still off; the links come out empty, and — would it be too much to ask? — the footnotes are not included and formatted.
For instance, this excerpt from Wikipedia:
… comes out as:
**Democracy** ( **, literally "rule by people"), in modern usage, has
three senses all for a system of government where the citizens exercise
power by [voting]. In a [direct democracy], the citizens as a whole form
a governing body, and vote directly on each issue, e.g. on the passage
of a particular tax law. In a [representative democracy] the citizens
elect representatives from among themselves. These representative meet
to form a governing body, such as a [legislature]. In a [constitutional
democracy] the powers of the majority are exercised within the framework
of a representative democracy, but the constitution limits the majority
and protects the minority, usually through the enjoyment by all of
certain individual rights, e.g. freedom of speech, or freedom of
association.[1][2] Democracy is sometimes referred to as "rule of the
majority".[3] Democracy is a system of processing conflicts in which
outcomes depend on what participants do, but no single force controls
what occurs and its outcomes.
