mentions UTF-8 everywhere - except in the text frame!

So should we  alter the IAX spec to specify the null byte is  
mandatory in a text
frame and drop any that don't have '\0' as the last byte?
I.e. enforce C's choices on IAX, but only in a single message type ????
Or should the IAX channel driver silently add a '\0' ?

:-) Ah, but it helps us find bugs!

(We were converting to utf-8 just not adding the null byte.)
