Hmmm. What about package?

    It's not clear that changing packages counts as a scope since it doesn't affect lexical variables:

    package SomePackage; my $foo = "bar\n"; package main; print $foo; # prints 'bar'

    I could be wrong about the formal definition of a "scope", though. We'll have to leave that up to the judge. :)

[Corion]: Yaerox: That's a somewhat hard problem. Encode solves the conversion part, but for guessing what encoding a file is in, that's the hard part
[Corion]: Yaerox: There is Encode::Guess, but that needs a limited set of inputs, and it also cannot handle multiple single-byte encodings
[Corion]: If you have a BOM, that's a really easy way to recognize UTF-8. Otherwise, you can try to decode a file from UTF-8, and if that works OK and doesn't crash, most likely the file was valid UTF-8
[Corion]: But as "ansi" (Latin-1?) is a single-byte encoding, any file is a valid ANSI file
