When Western names are printed in Last, First order, it would be nice if a comma were inserted. In the case of users of Asian languages, however, this would not be desirableso I suggest the following fix for the fullname function in moodlelib:

} else if ($CFG->fullnamedisplay == 'lastname firstname') {

if ( strpos(( ja,zh,ko),substr($CFG->lang,0,2)) > 0)

else

return $user->lastname$usecomma $user->firstname;
