Prototype AJAX picking up Wrong response from PHP

Answer 1

I'd use a tool such as FireBug or Charles to evaluate the traffic coming from your PHP script (unless you've already done that). If all is well, check inside of the client code, using alert() statements to see when the incorrect translation happens to confirm your Prototype suspicions.

Answer 2

I decided to rewrite the script in JQuery and it worked just fine. I came close to getting it to work in Prototype using encoding types but it would add a accent before each pound sign which was not good enough.

So now I rewrote it everything works perfect without a clitch.
