Answering myself, after benefitting of Ikegami's suggestion about where to look.

As almost always, CPAN has a solution and this time it is Unicode::UCD. So I can write

$ perl -e 'use Unicode::UCD qw(charinfo); use Data::Dumper; print Dump
+er( charinfo( ord("é"))), "\n";'


$VAR1 = {
          'digit' => '',
          'bidi' => 'L',
          'category' => 'Lu',
          'code' => '00C3',
          'script' => 'Latin',
          'combining' => '0',
          'upper' => '',
          'name' => 'LATIN CAPITAL LETTER A WITH TILDE',
          'unicode10' => 'LATIN CAPITAL LETTER A TILDE',
          'decomposition' => '0041 0303',
          'comment' => '',
          'mirrored' => 'N',
          'lower' => '00E3',
          'numeric' => '',
          'decimal' => '',
          'title' => '',
          'block' => 'Latin-1 Supplement'
        };

et voilá.. :) Thank You, that's all I was looking for.
