G'day tos,

Adding some additional code to print values and improve output, and a -C (see "perlrun: -C") so I don't see garbled output, I get: 

$ perl -C -wE 'use Unicode::GCString;use Unicode::Normalize;$t="Hütte"
+; say "\$t[$t]"; print length("$t"), "\n";$g=Unicode::GCString->new("
+$t"); say "\$g[$g]"; print $g->columns, "\n"; say $g->chars;'

[download]
$t[Hütte]
6
$g[Hütte]
6
6

If I then tell Perl that the source code is written in UTF-8 (use utf8;): 

$ perl -C -wE 'use utf8; use Unicode::GCString;use Unicode::Normalize;
+$t="Hütte"; say "\$t[$t]"; print length("$t"), "\n";$g=Unicode::GCStr
+ing->new("$t"); say "\$g[$g]"; print $g->columns, "\n"; say $g->chars
+;'

[download]
$t[Hütte]
5
$g[Hütte]
5
5

Both of those outcomes seem reasonable to me. Does that help you at all? If not, please explain why you were expecting a 6 then a 5.
