I have seen mention in some places that javascript's escape() misses single and
double quotes, the / and + characters... !!

What is escape() returning, on the client?

If the + is unescaped, you could try something like:
escape(str).replace(/\+/g, '%2B')

Another point, have you tried doing same with GET, and appending the params as
querystring to your URL? With POST, your are sending the params as content,
that should be encoded as per your content-type -- not sure if escape() is what
should be used for this.

Have you checked what the server side HTTP request is receiving as raw form
data?
