Perl Unicode Cookbook: Decode @ARGV as Local Encoding

Apr 26, 2012 by Tom Christiansen

℞ 14: Decode program arguments as locale encoding

While it may be most common in modern operating systems for your command-line arguments to be encoded as UTF-8, @ARGV may use other encodings. If you have configured your system with a proper locale, you may need to decode @ARGV appropriately. Unlike automatic UTF-8 @ARGV decoding, you must do this manually.

Install the Encode::Locale module from the CPAN:

    # cpan -i Encode::Locale
    use Encode qw(locale);
    use Encode::Locale;

    # use "locale" as an arg to encode/decode
    @ARGV = map { decode(locale => $_, 1) } @ARGV;
