Unicode values in cookie makes cookies corrupted in WKWebView

Unicode values in cookies creating issue while loading the page url inside the iOS application.
Web view is failing every time while reading the cookies and return my web page to login screen.

Flow of app:
We are using Chinese characters in the user name. Once we launch the url in native app webpage, cookies contains the username with it as provided, but it converted to unicode which makes cookies corrupted.

Can anyone help me on this?

Thanks in advance.
