are you running windows?
im guessing those are newline characters in windows format that arent
getting interpreted correctly on the
client side. you might try stripping out the newline characters prior to
encoding the data.
$jsonOut = json_encode(utf8_encode(str_replace("\r\n", '',
$stringToEncode)));
also, what are you trying to encode? if you are encoding arrays or objects
(php that is) you will have to
utf8_encode all the elements of those complex datums prior to handing them
to json_encode() for
the final output.
