I have a line of code which appears to cause my unassigned utf8 program to hang: 
$filename = "myfile";
print "\nThis program uses a real expression found on http://www.regul
+ar-expressions.info/unicode.html#category";
open( my $fh, '< :encoding(UTF-8)', $filename ) or die "Cannot open $f
+ilename: $!";
    while ( my $line = <$fh> ) {
         if ( $line =~ /\p{Unassigned}+/ ) {
            print "$line\n";
        }
    }
print "\nThis program uses a real expression found on http://www.regul
+ar-expressions.info/unicode.html#category";
close $fh;

The line "  if ( $line =~ /\p{Unassigned}+/ ) {" seems to be the culprit. When I replace the category expression with any other /\p expression the program runs fine. Is there extra code needed for the unassigned category?

Remember you are working with a newbie. Any help appreciate.
