[Plugin: Redirection] Broken encode/decode on Apache redirects?

When entering an url to redirect to in the Apache module it saves to .htaccess with encoded special chars (=+? to the % ones). When I use the link though the decoding fails and none of the special characters show in the resulting url.

If I replace the link in the .htaccess file directly with the non-encoded url it works fine (but the plugin will overwrite once any edits are made).

Is there an option where I can tun off encoding for Apache links?

Thanks!
