backticks send the executed program's STDOUT to a variable, and system sends it to your main program's STDOUT. So it could depend on what your main program's STDOUT is connected to. If it's connected to something that blocks, for example, or something that returns an error when you write to it, that could explain the problem.

    [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
