[Catalyst] Catalyst::Controller:REST and JSON vs JSONP issue

So it turns out there are certain characters that are perfectly legal
JSON that are NOT legal JavaScript:


We have run into this problem in our application which uses
Catalyst::Controller::REST to output certain data as JSON or JSONP.

Catalyst::Controller::REST first encodes the data as JSON, and then to
create JSONP, simply wraps the JSON in a callback function, and no
attempt is made to deal with possible illegal characters.

I believe a solution would involve replacing the illegal characters in
Catalyst::Action::Serialize::JSON before the string is wrapped in the
callback function.

Has anyone else run into this problem?
