The data type of the DSPLY_NMLL field is RMTES_STRING whose data is encoded with the Reuters Multilingual Text Encoding Standard (RMTES). RMTES uses ISO 2022 escape sequences to select the character sets used.

The TibMsg API provided in the RFA package provides conversion functionality to convert RMTES encoded strings received through Market Feed connections to Unicode string. The functions are TibMsg::ConvertToUTF8() which converts MarketFeed string data to UTF8 string data and TibMsg::ConvertToUCS2() which converts MarketFeed string data to UCS2 string data. For more information, please see the “12.3.13. TibMsg::ConvertToUCS2, TibMsg::ConvertToUTF8” section in the TibMsg API programming guide document (tmsgapi.pdf) provided in the RFA C++ package.

For other APIs, please see the information in this question.

Please see the following codes for the example code.

  err = tMsg.Get("DSPLY_NMLL",  fldTmp);

  if (!err.code)
  {
      char str_data[512];
      if (fldTmp.Type() == TIBMSG_STRING && fldTmp.HintType() ==
  TIBMSG_NODATA) 
      {
           printf("%s:  \n", fldTmp.Name());
           strncpy(str_data, (char*)fldTmp.Data(), fldTmp.Size());
           str_data[fldTmp.Size()]  = '\0';

           printf("String data : %s\n", str_data);
           Tib_i32  conv_len = 0;
           
           // UTF8 - 1 char can be 3 chars
           char *UTF8_data = new char[(fldTmp.Size()  * 3) + 1];
           TibErr err = TibMsg::ConvertToUTF8((char*)fldTmp.Data(), fldTmp.Size(), UTF8_data,(fldTmp.Size() * 3) + 1, conv_len);
  
           // UCS2 - 1 char can be 2 chars
           unsigned short*  ucs2_data = new unsigned short[(fldTmp.Size() * 2) + 1];
           err = TibMsg::ConvertToUCS2((char*)fldTmp.Data(), fldTmp.Size(), ucs2_data,(fldTmp.Size() * 2) + 1, conv_len);

           delete[] UTF8_data;
           delete[] ucs2_data;
           printf("\n"); }
       }
