G'day perlpearls,

Welcome to the monastery.

I agree with derby's comments above. I was interested to see how this might be achieved with MIME::Lite so I ran some tests. Having now seen your subsequent response, I realise that this isn't what you were after; however, someone might find it useful.

Here's my test code:

$ perl -Mstrict -Mwarnings -e '
    use utf8;
    use MIME::Lite;
    package MIME::Lite::IO_Handle {
        no warnings "redefine";
        sub print {
            my $self = shift;
            binmode $$self => ":utf8";
            print {$$self} @_;
        }
    };
    MIME::Lite::->new(
        To => "ken",
        From => "ken",
        Type => "text/plain; charset=utf8",
        Subject => "\x{263a} Happy days!",
        Data => "Testing 1 2 3",
    )->send;
'

Notes:

• use utf8; — because there's a Unicode character in the source code.
• package MIME::Lite::IO_Handle { ... } — to deal with message "Wide character in print at /.../MIME/Lite.pm line 3164 ...". The only change to the original method is the addition of binmode $$self => ":utf8";.
• \x{263a} — that's a smiley face. (The sad face \x{2639} also worked.)

Here's the mail that arrived:
