How to disable the automatic urlencode of hyperlinks

Hi!

Hyperlinks inside a page are automatically urlencoded when loading the editor. But i want to be able to set hrefs that are not urlencoded. In my case, I'd like to put some php code inside - e.g. <?=$this->url("foo")?>.

I tried to set the protectedSource option to ignore php code, but it seems, that this does not affect the urlencoding. And yep, I'm sure, the regexp is correct - /(.*?)(\<\?.*?\?\>)(.*?)/si

Thanks for your response!
