result strings. In PEP 393, a buffer must be scanned for the

This may be a silly question: are there things in place to optimize
this for the case where two strings are combined? E.g. highest
character in combined string is max(highest character in either of the
strings).
The "double-scan" issue is only for codec decoders.
If you combine two Unicode objects (a+b), you already know the highest
code point and the kind of each string.
