thank you for your answer! sorry,I am use telephony sms for sending and receiveing chinese sms, but it's disordered coding with all coding mode(five kinds)
/* kTelSms8BitsEncoding 0 8-bit encoding. kTelSmsBitsASCIIEncoding 1 ANSI X3.4 encoding. kTelSmsIA5Encoding 2 CCITT T.50 encoding. kTelSmsIS91Encoding 3 TIA/EIA/IS-91 section 3.7.1 encoding. kTelSmsUCS2Encoding 4 UCS2 encoding; used with GSM only. kTelSmsDefaultGSMEncoding */ Can you tell me if it's must use TxtConvertEncoding function?
If what must use TxtConvertEncoding? I'm assuming you're trying to run on pre-5.3 versions of Palm OS. If so, then my previous suggestion is the only work-around I can think of, unless you're bypassing SMSLib or writing your own library.

In China, SMS is encoded using UCS-2. In Taiwan, the encoding is GSM if the message only contains 7-bit ASCII, otherwise it also uses UCS-2.
Versions of SMSLib prior to Palm OS 5.3 don't support UCS-2, IIRC. You might be able to get it to work properly by converting to UCS-2 yourself (using TxtConvertEncoding), then send it as 8-bit raw, which I believe is supported.
I don't know what would happen on the receive size when older versions of SMSLib get sent UCS-2.
