UTF8 question

Hi there,
I am sending my Wiser a MEDIATRANSPORT TRACK_NAME command via a CGate Connection and multibyte UTF-8 characters seem to kill it:

Take the song
The Anchor Song - Bj?rk
which corresponds to these Unicode wide characters:
54 00 68 00 65 00 20 00 41 00 6e 00 63 00 68 00 6f 00 72 00 20 00 53 00 6f 00 6e 00 67 00 20 00 2d 00 20 00 42 00 6a 00 f6 00 72 00 6b 00 00 00

(The o after the j has an umlaut on it.

In UTF-8 this:
The Anchor Song - Björk

or expressed in bytes
54 68 65 20 41 6e 63 68 6f 72 20 53 6f 6e 67 20 2d 20 42 6a c3 b6 72 6b 00

I also see the message in the Toolkit log expressed as:
26/07/2015 16:50:24.832,192,Media Transport Control,1,Master Bedroom,21,PCINT,"Track Name: "The Anchor", Next, (packet 1 of 3)"
26/07/2015 16:50:24.932,192,Media Transport Control,1,Master Bedroom,21,PCINT,"Track Name: "Song - Bj??", Next, (packet 2 of 3)"
26/07/2015 16:50:24.992,192,Media Transport Control,1,Master Bedroom,21,PCINT,"Track Name: "rk", Next, (packet 3 of 3)"

implying it has not understood the UTF-8-either.

However, the bigger problem is that this string seems to send the Wiser into an infinite loop of some sort as once it receives it it stops accepting requests and needs the plug to be pulled....

Ashleigh,
Thanks - I have swapped the text round so it becomes
Bj?rk - The Anchor Song

so that the Bjork is firmly inside the 11 byte message and the problem occurs for that too.

One other comment - my code is splitting the string on the 11 byte marks (per the documentation) into the packets not C-GATE.

Thanks

Mark

 

Daniel,
Hi there. You can call me Mark

I am sending the following three commands:
(in each case expressed as a string or as a byte sequence)

Also, while we are playing around in here if the last character in a fragment is a space it doesn't get propagated! - would be better to double quote the string
