Is there any way to know whether the kanji are in Japanese or Chinese?

I use Japanese input method to type out the kanji, but ASCII display is Chinese pinyin.

This crate's algorithm is too primitive to handle Japanese. It doesn't have any context at all, and can't handle characters that have multiple pronunciations.
