in reply to Guess between UTF8 and Latin1/ISO-8859-1

In perluniintro, under the "Questions with Answers" section, there is an example of how to check if a string contains Unicode. It comes with a big warning that you really don't want to do this . . .

I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident.

    It seems you meant the response to the "How Do I Know Whether My String Is In Unicode?" question, right? Well I don't care whether Perl thinks the string is unicode (I know it does not), I want to know whether the string of bytes is "could be" UTF-8. Anyway the later answers seem to be what I need. I did try the pack() solution and it seems to be working fine.

    I'll try several ways suggested in that manpage and by other responders and come back with some benchmarks :-)
