Nesting of objects in json::parse

[Kolhun]

Hello everyone, tell me there is a string, I translate it into JSON (json::parse). The question is that the keys I need are located in the "data" object how do I access the keys that are located in it? And work directly with it

By the way, why does the "name" key return strange characters to me? When does the original line look like in the screenshot below? The idea should be Cyrillic

Make sure the input is UTF-8.

Sorry, from the other plugin everything is ok, but from the json side will it be so
