Re: What does it mean to "not be a valid string in Unicode"?

[Stephan Stiller]

A Unicode string in UTF-8 encoding form could be ill-formed if the bytes don't 
follow the specification for UTF-8, for example.
Given that answer, add "in UTF-32" to my email just now, for 
simplicity's sake. Or let's simply assume we're dealing with some sort 
of sequence of abstract integers from hex+0 to hex+10FFFF, to abstract 
away from "encoding form" issues.
