No. `use utf8;` tells Perl that the source code contains UTF-8 characters (and you can use them in identifiers, too). It's in no way related to how external data are encoded/decoded.

Quite right, of course. But I was surprised today while playing with using the official name for Unicode characters to find that it's not needed in that case: `use strict; use warnings; use feature 'say'; #use utf8; use open qw( :encoding(UTF-8) :std ); say "\N{FATHER CHRISTMAS} thanks you for all your hard work tonight"; __END__` [download] 🎅 thanks you for all your hard work tonight use strict; use warnings; use feature 'say'; #use utf8; use open qw( :encoding(UTF-8) :std ); say "🎅 thanks you for all your hard work tonight"; __END__ đŸŽ… thanks you for all your hard work tonight The way forward always starts with a minimal test.

Well, spend a little time in the PerlMonks Chatterbox and you'll learn something ... To answer my question above, see charnames: "Pragma use charnames is used to gain access to the names of the Unicode characters and named character sequences ..." "Starting in Perl v5.16, any occurrence of \N{CHARNAME} sequences in a double-quotish string automatically loads this module ..." Thanks choroba for pointing to this pragma. The way forward always starts with a minimal test.	[reply]

`use utf8;` simply tells Perl that your source code is encoded using UTF-8 (as opposed to ASCII). It would have no effect in my program. Furthermore, the subs provided by the module are always loaded, so I don't need to explicity load the module (`use utf8 ();`) to access them.	[reply] [d/l] [select]

"...no effect..." Yes. Thank you very much ikegami 👍. choroba already advised. Best regards, Karl ŤThe Crux of the Biscuit is the Apostropheť `perl -MCrypt::CBC -E 'say Crypt::CBC->new(-key=>'kgb',-cipher=>"Blowfish")->decrypt_hex($ENV{KARL});'`Help	[reply] [d/l]
