This example shows how you can use pass through character (PTC) literals in a session with Unicode Pass Through enabled. The PTC literals are emoji characters, and the session character set is UTF16.

To run these examples, replace the emoji graphics with the corresponding Unicode code points (such as U+1F601) inserted using your client application.
