All good replies
It means the program needs to go back (a.k.a. "back up")
but I'd say "backtracking" would make for better wording in TUS.
I tend to disagree, because "back up" seems to me the one expression
that people dealing in code point conversion and string access would use
in this context. Not something that TUS should redefine.
There simply are two meanings for the word "backup", which in and of
itself is nothing unusual, especially where one of them is the ordinary
sense of the term (not really a technical term).
The text in question is not exactly new to Unicode 6.2, probably goes
back to around the time
UTF-8 and UTF-16 were added over a decade ago. Getting a single question
on this passage after all these years would seem to indicate that
confusion isn't exactly rampant.
