Wikipedia Markdown link throws a 'Bad request' error

[ericdke]

Hi! Posting this Markdown link creates a 'Bad request' error:

[Dunning Kruger effect](http://en.wikipedia.org/wiki/Dunning–Kruger_effect)

with all clients I tried.

Although other similar links are properly parsed, like this one:

[Peter principle](http://en.wikipedia.org/wiki/Peter_Principle)

Thanks!

Sail does this fine, though - it handles the markdown correctly and sends the output fine.

Examples:

• 1 - this link: http://en.wikipedia.org/wiki/Dunning–Kruger_effect
• 2 - this link: http://en.wikipedia.org/wiki/Fisher–Yates_shuffle

Both were using the Wikipedia links with a "–" in them and worked fine.

EDIT: Sail uses this library for the Markdown - GitHub link - which is why it works when the API doesn't.
