if (!$this->getAttributeGroupCode()) {
    $groupName = $this->getAttributeGroupName();
    if ($groupName) {
        $this->setAttributeGroupCode(trim(preg_replace('/[^a-z0-9]+/', '-', strtolower($groupName)), '-'));
    }
}

For example, the algorithm return null (exactly null, not empty string) then the group name is in Cyrillic.

This leads to the bugs:
