"But not Hindi, Arabic, Bengali or Russian,"
Having worked at Microsoft*, I find it ironic it doesn't work with those languages since the vast majority of dev work is performed by outsourcing / body shops in India and Indonesia with a lot of the Senior Devs coming out of Russia after the fall of the USSR. Not too many Bengali folk, but they at least out-number Americans by a wide margin.
