Hello again Monks, i have a problem with TTFMetrics giving me a wrong values for unicode strings.

here's an example:
/the string doesn't show properly in the code section, so here it is "بلحة"/
use warnings;
use strict;
use Font::TTFMetrics;
use utf8;


 my $metrics = Font::TTFMetrics->new("Arial.ttf"); #16px
 my $str_en = ($metrics->string_width("Balha") * 1152) / (147456);
 my $str_ar = ($metrics->string_width("بلحة") 
+* 1152) / (147456);
 my $str_ar2 = ($metrics->string_width("\x{0628}\x{0644}\x{062D}\x{062
+9}") * 1152) / (147456);
 
 print ('My English string: ' . "$str_en" .  "px\n");
 print ('My Unicode string: ' . "$str_ar" . "px\n");
 print ('My Unicode string 2: ' . "$str_ar2" . "px\n");

the output is:
My English string: 40.921875px
My Unicode string: 33.0390625px
My Unicode string 2: 33.0390625px

the width value of the english string is correct. and for the unicode string is wrong and should be 21 px.
is there something i should do to make it right?
