sounds very simple.
:r /tmp/g2
use utf8;
use Encode;
my $s = 'abcäöüß$€✓XYZ';
print "full: ", encode ('UTF-8', $s), "\n";
$s =~ tr/\000-\377//cd;
print "latin1 only: ", encode ('UTF-8', $s), "\n";
$s =~ tr/\000-\177//cd;
print "ASCII only: ", encode ('UTF-8', $s), "\n";
__END__
:r !perl /tmp/g2
full: abcäöüß$€✓XYZ
latin1 only: abcäöüß$XYZ
ASCII only: abc$XYZ
