for some reason, there are instances that special characters do show when you use this function, but when you revisit or refresh the page the special characters doesn't appear anymore, ie GRSARMERING is being displayed instead of GRÆSARMERING. You have to provide the second parameter which charset you are using to override the value. in my case it's iso-8859-1, so the function would now look like
mb_strtoupper($foo, 'iso-8859-1')
mb_strtoupper
