Earlier this month I mentioned having rec'd the definition for 
arrayEncoded data, at the bottom of this post:
<http://lists.runrev.com/pipermail/use-livecode/2012-April/170660.html>

While that article is still being finished, from what I've seen in Mark 
Waddingham's example code it seems that the only character we must avoid 
in array keys is NULL, since that's used internally as a delimiter 
between the key and the value.

As far as I can tell, all other characters are allowable.
