pjsip, including pjsua-lib, should allow Unicode message body, thanks to
pj_str_t which allows null character to appear in the string, so no
conversion to UTF-8 should be required by pjsip. I suppose you could do this
to send Unicode IM or any other binary content, but I have not tried this
myself:
pj_str_t content_type, content;
content_type = pj_str("whatever");
content.ptr = ... pointer to binary data;
content.length = ... length of binary data;
status = pjsua_im_send(acc_id, to_uri, &content_type, content, NULL);
In fact, it would be great if someone can indicate how utf-8 is support in

SIP is UTF-8 based protocol, and since UTF-8 is encoding friendly to the
good old C null-terminated string, there's nothing special in pjsip to
handle this.
SIP may contain binary message body, and this is also fine with pjsip since
pjsip does not generally process the message body, except SDP and PIDF/XML,
which are normally encoded in UTF-8 anyway.
pjsip itself always works in ANSI mode even on systems where the native
encoding is Unicode (such as WinCE or Symbian). Confused? ;-)
