in reply to Unicode combining characters as hash keys?


binmode(STDOUT, ':encoding(UTF-8)');

…instead of…

binmode(STDOUT, ":utf8");

Likewise, use…

open HASH, '<:encoding(UTF-8)', 'test_hash.txt'; ... open INPUTFILE, '<:encoding(UTF-8)', 'test_input.txt';

…instead of…

open HASH, '<:utf8', "test_hash.txt"; ... open INPUTFILE, '<:utf8', "test_input.txt";

Also, this looks wrong to me:

my @word = $entry =~ /(\X)/g;

Shouldn't that be…

my @word = $entry =~ /(\X+)/g;


UPDATE: Upon reexamination, it looks right to me. :-/ Using the variable name @letters instead of @word would be an improvement, though. Then…

for my $letter (@letters) { my @input_features = @{ $hash{$letter} }; print join(" ", @input_features) . "\n"; }

    Thanks, Jim.

    I didn't understand the part you crossed out either at first. I didn't know using /.../g would return an array. But I found in the Perl Cookbook :-)
