This question is an exact duplicate of:

The URL recognizer stops at the ' character, yet this is a valid character in URLs.

Example: http://en.wikipedia.org/wiki/Rice's_theorem

On a related note, wrapping the URL in <a href="..."> doesn't help either; somehow the sanitizing process filters out the URL it thinks is faulty:

<a href="http://en.wikipedia.org/wiki/Rice's_theorem">this is (not) a link</a>


<p>this is (not) a link</p>

(Currently: this is (not) a link.)

Instead, wrap it in Markdown syntax:


Produces http://en.wikipedia.org/wiki/Rice's_theorem

  • ...or make the editor do it for you: paste the URL, select it, hit Ctrl-L, paste it again. Of course, in this very example a nice text rather than the bare URL looks better anyhow! Like: "Wikipedia explains for Rice's theorem...". So: type that nice title, select it, hit Ctrl-L, paste the URL. – Arjan Apr 20 '11 at 10:21
