=head1 NAME
utf8::all - turn on Unicode - all of it
=head1 VERSION
version 0.010
=head1 SYNOPSIS
use utf8::all; # Turn on UTF-8. All of it.
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!
=head1 DESCRIPTION
L<utf8> allows you to write your Perl encoded in UTF-8. That means UTF-8
strings, variable names, and regular expressions. C<utf8::all> goes further, and
makes C<@ARGV> encoded in UTF-8, and filehandles are opened with UTF-8 encoding
turned on by default (including STDIN, STDOUT, STDERR), and charnames are
imported so C<\N{...}> sequences can be used to compile Unicode characters based
on names. If you I<don't> want UTF-8 for a particular filehandle, you'll have to
set C<binmode $filehandle>.
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!
=head1 INTERACTION WITH AUTODIE
If you use L<autodie>, which is a great idea, you need to use at least version
B<2.12>, released on L<June 26, 2012|https://metacpan.org/source/PJF/autodie-2.12/Changes#L3>.
Otherwise, autodie obliterates the IO layers set by the L<open> pragma. See
L<RT #54777|https://rt.cpan.org/Ticket/Display.html?id=54777> and
L<GH #7|https://github.com/doherty/utf8-all/issues/7>.
