NAME ^

utf8::all - turn on Unicode - all of it

VERSION ^

version 0.015

SYNOPSIS ^

    use utf8::all;                # Turn on UTF-8, all of it.

    # Also provide UTF-8 versions of functions from...
    use utf8::all qw(File::Find); # File::Find
    use utf8::all qw(Cwd);        # Cwd
    use utf8::all qw(:all);       # everything

    open my $in, '<', 'contains-utf8';  # UTF-8 already turned on here
    print length 'føø bār';             # 7 UTF-8 characters
    my $utf8_arg = shift @ARGV;         # @ARGV is UTF-8 too (only for main)

DESCRIPTION ^

utf8 allows you to write your Perl encoded in UTF-8. That means UTF-8 strings, variable names, and regular expressions.

utf8::all goes further:

Import options ^

If you provide the File::Find or Cwd options to the use utf8::all line, those modules are loaded if they haven't been already, but you will get UTF-8-ified versions instead of the normal ones. This effect is lexical.

File::Find

find and finddepth

Cwd

cwd, fastcwd, getcwd, fastgetcwd

abs_path, realpath, fast_abs_path

Use use utf8::all qw(:all) to get all of these, plus whatever we dream up in the future.

Lexical scope

The pragma is lexically-scoped, so you can do the following if you had some reason to:

    {
        use utf8::all;
        open my $out, '>', 'outfile';
        my $utf8_str = 'føø bār';
        print length $utf8_str, "\n"; # 7
        print $out $utf8_str;         # out as utf8
    }
    open my $in, '<', 'outfile';      # in as raw
    my $text = do { local $/; <$in>};
    print length $text, "\n";         # 10, not 7!

INTERACTION WITH AUTODIE ^

If you use autodie, which is a great idea, you need to use at least version 2.12, released on June 26, 2012. Otherwise, autodie obliterates the IO layers set by the open pragma. See RT #54777 and GH #7.
