I'd recommend you to take libcurl development talk over to the curl-library
list where you'll find many other libcurl-using developers. This reply is
cc'ed over there.

I don't believe you're right when saying this. Can you post a VERBOSE or
DEBUGFUNCTION output that proves this?

libcurl doesn't strip anything. It sends whatever you tell it to send.

I do however find it very unlikely that you should put the whole POST data
within double quotes the way you do. Why does your string begin and end with
\" ?

Why do you convert them like that? The data you send in a POST is supposed to
be URL-encoded in case they can't be sent as-is.

' should become %27 and " should become %22 if you don't want to send them.

I believe you get VERBOSE sent to stderr. Use DEBUGFUNCTION to deal with it
the way you think fits better.

If you want to, yes.

Of course. Make a write callback that receives all data instead of the
default, and then don't do anything in the callback except return the correct
value back to libcurl.
