Is this currently affecting your production site or did you revert to a previous version?
seems to be working at the moment.
I'm getting very close to a new release but if your site is broken I can try to produce a build for you right away.
I do recommend changing this to false
<add key="AlwaysUrlEncode" value="false" />
I made it true by default in version 188.8.131.52 but I am changing it to false in the coming release because it seems to have caused more problems rather than fixing the one it was intended to fix.
