But things like hier can ne tricky, because unless the pronounciation is super exaggerated, it could easily be hir. Is it is Eumel or Oimel or Oymel? Is it Ei or Ai? It could be ain Ai im Ayerbecher!

Oh no, what have you done?!?! I don't hear the difference between i and ie, or ei and ai but it just looks so, so wrong.

I didn't even think about dialects! Omg, that would be unreadable.
