int KeyPressEventIsTrailByte (int eventData2);
Call this function when you receive an EVENT_KEYPRESS in a panel or control callback to determine if the callback's eventData1 parameter contains the second byte of a two-byte character. If the callback's eventData1 parameter contains a trail byte, you can call GetKeyPressEventCharacter to get both bytes of the character.
