range operator vs. unicode

Porters,

I found that ('a'..'z') works only for alphanumerals.  Try the code  
below;

use strict;
use warnings;
#use utf8;
use charnames ':full';
binmode STDOUT, ':utf8';
# works
print "$_\n" for ("\N{LATIN CAPITAL LETTER A}" .. "\N{LATIN CAPITAL  
LETTER Z}");
# (0..9, 'A'..'Z', 'a'..'z'); symbols skipped
print "$_\n" for ("\N{DIGIT ZERO}" .. "\N{LATIN SMALL LETTER Z}");
# does not work
print "$_\n" for ("\N{LATIN SMALL LETTER A}" .. "\N{LEFT CURLY  
BRACKET}");
print "$_\n" for ("\N{NO-BREAK SPACE}" .. "\N{LATIN SMALL LETTER Y  
WITH DIAERESIS}");
print "$_\n" for ("\N{GREEK CAPITAL LETTER ALPHA}" .. "\N{GREEK  
CAPITAL LETTER OMEGA}");
print "$_\n" for ("\N{KATAKANA LETTER SMALL A}" .. "\N{KATAKANA  
LETTER VO}")
__END__

There is an easy workaround, however.

my @katakana = map { chr } ("\N{KATAKANA LETTER SMALL A}" .. "\N 
{KATAKANA LETTER VO}");


Since we have a workaround above, I don't consider this range  
implementation is a bug -- after all we would be rather surprised if  
('\x0' .. '\x{10FFFF}') worked.  But the following should be fixed so  
greeks are not confused with the consequence of  ("\N{GREEK CAPITAL  
LETTER ALPHA}" .. "\N{GREEK CAPITAL LETTER OMEGA}"), japanese are not  
confused with ("\N{KATAKANA LETTER SMALL A}" .. "\N{KATAKANA LETTER  
VO}") and so forth.
