Thanks for your reply, Martin.

Out of curiosity, is there any point in trying both ASCII and UTF-8?  UTF-8
is a strict superset of ASCII, so shouldn't checking UTF-8 alone be enough
for both?  If we don't care what the original encoding was (we just want
Unicode text to process), does explicitly checking for ASCII buy us
anything?
