It looks good to me. I thought you would do json_string === s_kept, but you took it's substring at position 1 instead, I guess dump gives you an extra character in the beginning or something? |

Yes, dump adds quotes. |

Just for me to understand, how would this behave exactly? If there is a 0×dc byte for example, it will be escaped as \334 octal string (or \xdc hex, or similar)?
I think the important thing is to not break the json format.
And also what about other UTF-8 accepted chars? Like \b or \t handled below: how will they be dumped in this case?
I have limited access these days (from mobile), and I don't know exactly the purpose of ensure_ascii and its default value. If you could provide some hint it would be helpful.
Thank you

Oh, you're right! Just copying the input to the output is wrong here, because valid characters like LF that must be escaped to \n would not be escaped and the resulting JSON would be invalid. Thanks for noting. I will fix this.

Add an enumerator
keeptoerror_handler_tto allow to keep the input as-is in case of UTF-8 errors.Fixes #4552
