Does anyone know what languages Apple supports? The docs don't have a list. Tesseract might be "meh" but it is probably the best open source option available for devnagari scripts or Persian, for example.
I've used it on a number of Cyrillic languages (Russian, Bulgarian, etc), Hungarian, Turkish, along with the typical ones (Spanish, German, French, Italian, Portuguese). I've heard it supports Chinese. I just tried Persian and devnagari samples on my Mac and it could not do either.
