No audio pronunciation, no special letters – World Travel Numbers Guide (AE,CN,FR,DE,IN,IT,JP,KR,ES,TH,TR) Review

Bought it because I'm traveling soon to Istanbul and I'm learning a little turkish. Downloaded this app to my iPad. The button for audio pronunciation does not work. AND there are no special characters like ü, ö, and letters like c with the little squiggly tail. I spent a lot of time learning the alphabet, so if I am pronouncing ü like u then that is a huge mistake.
