unicode在Objective-C中转义

问题描述

我有一个字符串Artîsté".我在PHP上使用了json_encode，并得到了"Art \ u00eest \ u00e9".

I have a string "Artîsté". I use json_encode from PHP on it and I get "Art\u00eest\u00e9".

如何将其转换为NSString?我已经尝试了很多东西，但都无济于事，我总是最后得到Artîsté

How do I convert that to an NSString? I have tried many things and none of them work I always end up getting Artîsté

For Example:
NSString stringWithUTF8String:"Art\u00c3\u00aest\u00c3\u00a9"];//Artîsté
@"Art\u00c3\u00aest\u00c3\u00a9"; //Artîsté
