Richard Coppen updated MQTT-44:
-------------------------------
Affects Version/s: 3.1.1
set version to 3.1.1
> Specific details for UTF-8 Strings
> ----------------------------------
>
> Key: MQTT-44
> URL: http://tools.oasis-open.org/issues/browse/MQTT-44
> Project: OASIS Message Queuing Telemetry Transport (MQTT) TC
> Issue Type: Improvement
> Components: core
> Affects Versions: 3.1.1
> Reporter: Rahul Gupta
>
> This issues is based on comments in MQTT-24, and is opened a Core issue to discuss in MQTT TC Call, I had a discussion with my co-editor Andy and he suggested to open a core issue for TC discussion.
> from MQTT-24
> -------------------
> > We should also make a simple statement that UTF-8 encodings MUST NOT have a three character initial BOM.
> > A clarification that the encoding MUST NOT be Java's Modified UTF-8, and can contain ASCII NULL
> > At the same time, it's probably worth nothing too that certain unicode combinations are invalid in UTF- 8 - the use of surrogate pairs from UTF-16 re-encoded and certain non-transmissable characters (eg U+FFFE from memory) - these normally delimit the last 2 characters in a multi-lingual plain. These restrictions are only a minor burden fro java implementations using the naive methods in string / character. These restrictions serve to stop propagation of bad data through a network of nodes.
> > Implementations MAY decide to not support the use of ASCII NUL and C0 / C1 control codes / MAY decide to place additional restrictions on supported characters
