in thread Whether 'use utf8;' is good style

And I want to know whether there are pitfalls, when someone is using a module with that pragma probably expecting the good old byte string world.

What would you expect to happen in that case? (I can't imagine things working correctly except by accident.)

    Hi chromatic,

    does that mean you suggest avoiding use utf8; in public packages?

    Best regards
    McA

      Quite the contrary. If you have literal strings you intend for Perl to deal with in the UTF-8 encoding, you'd better use that pragma.

      If you're not explicit about Unicode and encodings, you're going to make a mess for other people to deal with. If you put UTF-8 in literals in your programs and don't use the utf8 pragma, you've acted irresponsibly.
