problem sending sms with carriage return

i'm trying to implement a php script interface to "http to sms"
i use urlencode to pass the message string to the gateway, but it seems that the gateway can't handle the messages containg a "new line" urlencoded.

passing an urlencoded string containg some encoded LFCR (%0D%0A) directly to the gateway leads to a 'sending' result key in json report, instead of 'success' string.
furthermore also the json string of the report result 'broken' by a new line.

i've seen that the built in sms sender interface can correctly handle new line inserted in the messages, so i hope that someone could give me some useful hints

Hi Lindali, I am also experiencng the same problem, can you also help us on our problem?

Thank you.

Have you trying to use the Escape character?

(char)0x1D

ASCII Control Codes:

academic.evergreen.edu/projects/biophysi...ogram/ascii_ctrl.htm

i tried prepending an urlencoded escape char (%1B) to a CR char.
No luck... the sms doesn't start.
an escape char only can be sent, but obviously it didn't result in any output in the sms

ok... if i put and urlencoded duble quotes into the sms, the gsm gateway correctly escapes it

if i put a line feed it is not escaped:
