It's something i've noticed a lot is that characters like Pocahontas and Esmeralda always get their names mispronounced por people.

Is there a reason for it? I know not everybody is good with names but it's bizarre how it's always the same names and the same mistakes that occur.

It's really strange because other "difficult" names like Jafar or Rapunzel don't get mispronounced that much. And it's not really a difficult name to mispronounce, at least we see how is Pocahontas' name written in the screen (the title). I'm guessing the thing with Esmeralda is people unfamiliar with Spanish, but still, it's a little bizarre.
