UNKNOWN-CTE — UNKNOWN-CTE

The server encountered an unknown Content-Transfer-Encoding in a message. It means a message has an encoding the server (or Riposte) didn't expect. This is uncommon and usually the server will still deliver the raw content. No specific fix via API—just be aware that a message might have an unusual encoding. Your application might need to handle it by using a different approach to read that message if content is garbled.
