Does it work on non-Latin scripts?

Upper/lower case only applies to Latin letters. Scripts without case, like Korean, are left unchanged.

What's the difference between Title Case and Sentence case?

Title Case capitalizes the first letter of every word, while Sentence case only capitalizes the first letter of each sentence (based on punctuation).
