Prevent decoding url after JSON.parse?

Question

JavaScript

Guys, tell me, please. I hope I explain correctly.
I receive a response from the server. There is a url like this: "\u041f\u041b000450".
After JSON.parse, this url is automatically decoded into the following form: "PL000450".
At the same time, this is the type of this data: "PL000450" I also need.
How to undo it? Or how to encode back and get this data "\u041f\u041b000450"?

Answer 1

\u041f
\u041b
These are just Unicode characters. Question removed.
