If I use a data: URI with backslashes in the data, the backslashes get canonicalized to forward slashes, which is incorrect.
<meta http-equiv="Content-type" content="text/html; charset=utf-8">
<object data="data:text/html;charset=utf8,<b>this</b> is a \'test'"></object>
The rendered text is:
this is a /'test'
Confirmed with WebKit 418.9 and ToT. This may be caused by a bug in another component of the operating system.

Fixed as bug 16692.
