Ajax encoding, what's the problem?

Question

JavaScript

The situation is the following.
Assembly ocStore, script prnt_scr.com/bip5je
Encoding utf-8 in the request prn_tscr.com/bip4yb
In the php script, bugs, all sorts of AddDefaultCharset, header(), explicit encoding in the ajax request do not help? mb_detect_encoding returns UTF-8.
Where to dig, who faced such a situation?

Answer 1

I don't know exactly what your problem is, but check the encoding of the php file.

Answer 2

Does the address bar confuse you or does the data come in gibberish?
Please describe exactly what is wrong.
