NAME
utf8::all - turn on Unicode - all of it
VERSION
version 0.011
SYNOPSIS
use utf8::all; # Turn on UTF-8. All of it. open my $in, '<', 'contains-utf8'; # UTF-8 already turned on here print length 'foo bXr'; # 7 UTF-8 characters my $utf8_arg = shift @ARGV; # @ARGV is UTF-8 too!
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, and makes @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 "\N{...}" sequences can be used to compile Unicode characters based on names. If you don't want UTF-8 for a particular filehandle, you'll have to set "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 = 'foo bXr'; 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 <https://metacpan.org/source/PJF/autodie-2.12/Changes#L3>. Otherwise, autodie obliterates the IO layers set by the open pragma. See RT #54777 <https://rt.cpan.org/Ticket/Display.html?id=54777> and GH #7 <https://github.com/doherty/utf8-all/issues/7>.
