@Random Ha. That's what I get for trusting the "potentially duplicate posts" feature of the question posting UI. Thanks. –  Anna Lear Feb 21 '11 at 16:51
    
Amazingly, I don't think any of those are exact duplicates; there's three about ", one about $, and one about ) –  Michael Mrozek Feb 21 '11 at 18:33
    
It should work with Markdown links now (in the editor as well) –  balpha Mar 7 '11 at 7:33

Because it can lead to some scripting exploits, we don't allow unencoded ' or " in URLs.

<http://en.wikipedia.org/wiki/Conway's_Game_of_Life>

Since Wikipedia supports workarounds for this and other problematic characters -- just omit them:

<http://en.wikipedia.org/wiki/Conways_Game_of_Life>
http://en.wikipedia.org/wiki/Conways_Game_of_Life

or properly encode it

Per the spec these chars are not allowed unencoded in URLs anyway

http://tools.ietf.org/html/rfc3986#section-2.2

  reserved    = gen-delims / sub-delims

  gen-delims  = ":" / "/" / "?" / "#" / "[" / "]" / "@"

  sub-delims  = "!" / "$" / "&" / "'" / "(" / ")"
              / "*" / "+" / "," / ";" / "="

Edit: This works fine now with Markdown links, i.e. using [bla](http://etc), the link button, Ctrl-L or similar.
