Permalink Bug with em-dashes - not sanitizing

[boldperspective]

If I were to create a post using long em dashes, the em dashes remain in the permalink

Example:
"Test — Post"

would become
"test-—-post"

I've seen that URL structure throw a 404 error one one of the servers I've worked on, but not every server.

Even if the 404 error wasn't a problem, that still looks like a dirty url to me.

Crap. Sorry.
