How to get readable Russian strings (instead of ASCII) in curl response?

Question

linux

curl -v -H "Content-Type: application/json" some_url

The response fields contain ACSII instead of Russian text (like \u0414\u0435\u0422).
Tried specifying other encodings in the request than my local utf-8, for example: Doesn't help.
-H "Content-Type: application/json; charset=koi-8"

Answer 1

JSON text exchanged between systems that are not part of a closed ecosystem MUST be encoded using UTF-8

Try the ascii2uni utility

curl -v -H "Content-Type: application/json" some_url | ascii2uni -aU
