Title:
  Group cloning fails - problem with multibyte UTF8

Status in Mahara:
  Confirmed

Bug description:
  If the user tries to clone a group named with special characters
  (mb4), the cloning will fail.

  The bug is in version 21.10.04 and maybe elsewhere.

  It is caused by an error in the lib/group.php script on line 377.
  Here, strtolower is mistakenly used instead of mb_strtolower.

  The code on the line should be:
  if (get_records_sql_array('SELECT id FROM {group} WHERE LOWER(TRIM(name)) = ?', array(mb_strtolower(trim($data['name']))))) {

  Same problem is in group/edit.php:

  on line 481. Correct code is here:
  if ($ids = get_records_sql_array('SELECT id FROM {group} WHERE LOWER(TRIM(name)) = ?', array(mb_strtolower(trim($values['name']))))) {

  line 497
  if ($ids = get_records_sql_array('SELECT id FROM {group} WHERE LOWER(TRIM(shortname)) = ?', array(mb_strtolower(trim($values['shortname']))))) {
