I tested with a 26 pages Chinese pdf and the answer is no, Tuchu only highlighted three English sentences.
This is weird, as Tuchu means highlight in Chinese.

Thanks for your feedback. In theory all languages should be supported since TextRank should be language-agnostic. Having said that, I think that my current sentence similarity strategy (by word overlap) is not a good fit for "symbol rich" languages such as Mandarin.
I am not Chinese (or from Asian descent) myself. Tuchu comes from some rainy Sunday Google translating. ;)
