You can eliminate the $i var by doing the following:

for (0 .. $#array) { print "$_ $array[$_]\n" }

Also, I would think you'd be better off using one of the other suggestions like for() or the x operator rather than map() for efficiency reasons.

    I like that... very clean, to the point, and quite readable. The only reason I chose map was to flex an all too atrophied brain muscle. :)

    Very funny Scotty... Now PLEASE beam down my PANTS!

[1nickt]: Yaerox probably best to whip up an SSCCE demonstrating the failure in what you have now and post to SoPW as a question.
[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
