I wonder why. I assume because they heavily use objective-c.
I have to hope it's at least 8-bit safe.
Spanish is one of the most widely spoken languages and accents can be removed and the result is perfectly understandable.
In Portuguese, which has more accents we also learned to live with systems that don't support them properly, yet caça and caca aren't the same, and the recipient better understand the limitation of the comunication medium.
