I agree compeltely. I think having text is bad idea, and if you have
text you can't really specify it to be "UTF-8 or ASCII" text...

If the text is there, you do need it to be UTF-8, and you do need
language tag.

I would simply remove it. If it is only stored in the log, then it it
is better to store that log entry in the local log file of the entity
sending this notify and when you need to know what that text was, you
can call the other end and ask what does your logs say when they
disconnected me at this time using UNSPECIFIED reason code...
