If a URL has spaces in it, the resulting post can come out looking quite strange.

There's no spaces in the URL, it's the parentheses. However, reddit's markdown engine is broken. If we check multiple other markdown rendering engines. The one thing we could do is url encode the (possibly) url encoded url again so reddit might render it correctly, but that could break the archive url.
