This is a follow-up to my related question Counting text with ligatures.

I have two columns of text which might contain a grapheme (such as ff, ffi). How can find a substring at a fixed column position, counting the graphemes as '1' each? In this example, I was hoping to print '0123456789' for each line.

Note: I inserted the code as pre-formatted, since the code-tag encodes the graphemes. I tried to fix using substr from Unicode::GCString, but that didn't work as I hoped. 

use strict;
use warnings;

use Unicode::GCString;

while (my $s = <DATA>){
	chomp($s);
	my $right = substr $s, 10;
	print $right, "\n";
	
#	my $gcs = Unicode::GCString->new($s);
#	my $right2 =  $gcs->substr(10);
#	print $right2, "\n";
}

__DATA__
01234567  0123456789
0123456ff  0123456789
0123456ffi  0123456789
012ff4ffi67  0123456789
