if ( $ALLOW_UTF8_FLAG && utf8::is_utf8( $text ) ) {
utf8::encode( $text );
}
This code won't work correctly with downgraded Latin1 strings.
In the example below f1() represent a way that most Perl core function work
with unicode.
and f2() represent a way your code works with it.
Results are different for downgraded Latin1 characters (but same for other characters)
use utf8;
use Devel::Peek;
my $text = "\xB5";
sub f1
{
my $s = shift;
open my $f, ">", "file1.tmp";
binmode $f, ":encoding(utf-8)";
print $f $s;
close $f;
}
sub f2
{
my $s = shift;
if (utf8::is_utf8( $s ) ) {
utf8::encode( $s );
}
open my $f, ">", "file2.tmp";
print $f $s;
close $f;
}
f1($text);
f2($text);
