Took me a while to understand what right and left quote meant 😅 Left quote: sentence(s) ending quote Right quote: sentence(s) starting quote And in 'process' fn: you're pushing all the characters inside the quotes to buffer.

It's been a while since I used state machines! I enjoyed the refresher =) Your implementation was great! It was also cool to see you handle Chinese characters. I do think you could have simplified the state machine to two states (e.g. InQuote and NotInQuote) rather than three. Something like this: case InQuote: if is_right_quote then flush buffer and state -> NotInQuote else add to buffer NotInQuote: if is_left_quote then state -> InQuote else continue
