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

19 Jun 2018

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:
