#MQTT Handling of Disallowed Unicode Code Points V1.0 published by MQTT TC

OASIS is pleased to announce publication of "MQTT Handling of Disallowed Unicode Code Points Version 1.0," a Committee Note from the members of the OASIS Message Queuing Telemetry Transport (MQTT) TC [1].

For users of MQTT, some combinations of MQTT Clients and Servers might allow one properly authorized publishing client to cause another client to disconnect by publishing a Topic Name that contains a disallowed Unicode code point. This document recommends some steps that can be taken to prevent this eventuality.

The Committee Note is available here:
