Links with caret ^ do not work?
An answer on super user had a link in it to a site with a caret character (
^) in the URL. Markdown was not rendering it as a link properly, likely due to some error in the link-detection regex. As a temporary fix, I made a goo.gl shortcut to the target URL and placed that in the answer, so it would render as a properly clickable link.
Edit: Based on the answer below, I have modified this to a feature request: can URLs submitted in a question or answer which have an invalid character like
^ be automatically encoded to the properly encoded form? This would prevent confusion by users, and would solve the problem of poorly formed URLs on other sites breaking this one. Many users may not be technically savvy enough to know that the URL they are trying to link to isn't actually valid, and this would be a way of preventing that from happening.
