use Encode qw( encode );

Of course, in most encodings (and UTF-8 in particular), U+0001 encodes as 01, so you can use an :encoding layer as normal. 

use open ':encoding(UTF-8)';

open(my $fh, '>', $qfn)
   or die("Can't create \"$qfn\": $!\n");

print($fh join("\x01", @values);

Finally, if the values are terminated by 01 rather than separated by 01, you'd use 

use open ':encoding(UTF-8)';

open(my $fh, '>', $qfn)
   or die("Can't create \"$qfn\": $!\n");

print($fh "$_\x01") for @values;

or 

use open ':encoding(UTF-8)';

open(my $fh, '>', $qfn)
   or die("Can't create \"$qfn\": $!\n");

local $\ = "\x01";
print($fh $_) for @values;

The last one might be tempting, but the global nature of the change to $\ could negatively affect code in modules.
