Errors occur in Japanese queries

[ghost]

"UnicodeEncodeError" occurs when trying to process a Japanese query.
Probably a wsgi error.

Can you give an example of which request are you doing, and how?
I tested doing some requests to micros with hiragana and kanji in the URL, and it seemed to work - at least as long as it's properly URL encoded.
It looks like the problem only happens with Flask - my Micro that worked was interacting via WSGI directly, but the another one running via Flask did the same error. The other ones I tested were probably either running on FastAPI or something else, but I have no idea

I used to use flask.
Japanese examples are "あああ", "こんにちは", etc.
Thank you for your answer
