Locale check doesnt consider Unicode strings: first letter case

Guys,

if i have a string like "Area" but the translation is "Área" (unicode), Coder wrongly detect it as different first letter case.

The fix to be placed on coder_i18n.inc, around line 123, replace:

    // Check the translation first capitable letter.
    if (ctype_upper($msgid[0]) != ctype_upper($msgstr[0])) {
      $rule = array(
        '#warning' => "The first letter in the translation text should have the same capitalisation as it's original text.",
      );
      _coder_error($results, $rule, $severity_name, $lineno, $msgstr);
    }

to

    // Check the translation first capitable letter.
    $first_msgid = drupal_substr($msgid, 0, 1);
    $first_msgstr = drupal_substr($msgstr, 0, 1);
    if (($first_msgid == drupal_strtoupper($first_msgid) and $first_msgstr != drupal_strtoupper($first_msgstr)) or
      ($first_msgid == drupal_strtolower($first_msgid) and $first_msgstr != drupal_strtolower($first_msgstr))) {
      $rule = array(
        '#warning' => "The first letter in the translation text should have the same capitalization as it's original text.",
      );
      _coder_error($results, $rule, $severity_name, $lineno, $msgstr);
    }

regards,
