Try utf8::all. It's not universal, because it handles only the core functionality, not libraries. Your use case can be much simplified, though. I strongly suspect you have too much code. Consider:
  • HTTP::Response provides both content (returns octets) and decoded_content (returns characters, appropriately decoded from Content-Type header).
  • decode_json wants to consume octets.
This means the following DWYW:
use LWP::UserAgent qw(); use JSON::MaybeXS qw(decode_json); my $ua = LWP::UserAgent->new; my $res = $ua->get('https://ru.wikipedia.org/w/api.php?action=query&fo +rmat=json&formatversion=2&list=allusers&auactiveusers&aufrom=%D0%91') +; die $res->status_line unless $res->is_success; my $json_OCTETS = $res->content; my $all_users_CHARACTERS = decode_json $json_OCTETS; my $continue_aufrom_CHARACTERS = $all_users_CHARACTERS->{continue}{auf +rom};
Your CGI script's templating system should take care to produce UTF-8 encoded octets. If you don't have one, then either one of
  • use Encode qw(encode); my $continue_aufrom_OCTETS = encode('UTF-8', $continue_aufrom_CHARACTE +RS, Encode::FB_CROAK); STDOUT->print($continue_aufrom_OCTETS);
  • binmode STDOUT, ':encoding(UTF-8)'; STDOUT->print($continue_aufrom_CHARACTERS);
is appropriate. The first variant is more robust.
