Fix ensure_ascii for json.dumps
Hi! This PR simply fixes all json.dumps. With ensure_ascii=False, unicodes can be properly serialized into JSON files in the modern days when UTF-8 is basically universal. This may also prevent silent behavioral bugs from LLMs, since they can hardly understand literal strings like "\u00x" except common ones.
Some cases do not necessarily need ensure_ascii=False, but they are added for consistency.
The PR hasn't been merged, so I can't evaluate it in Korean. I think it's a good PR—are there any reviewers available?
we did merge another PR for the same and is released with v0.2
