如何将encode编码成可读字符串？

Question

我从URL获取文本数据，并且有一个特定字符似乎无法正确编码 - ＆gt; ȭ

我知道那个角色是什么，所以我尝试手动将其编码为utf-8，但xcode甚至不识别该角色

NSLog(@"before: %@", brokenCharacter);
if([brokenCharacter isEqualToString: @"ȭ"]) brokenCharacter = @"A";
NSLog(@"after: %@", brokenCharacter);

我将NSLog视为：

before: ȭ
after: ȭ

这个问题会有解决办法吗？

Answer 1

可以使用NSUTF16BigEndianStringEncoding作为编码参数

NSString *brokenCharacter = @"ȭ";
NSLog(@"before: %@", brokenCharacter);
NSData *dataCharacter = [brokenCharacter dataUsingEncoding:NSUTF16BigEndianStringEncoding];
brokenCharacter = [NSString stringWithUTF8String:[dataCharacter bytes]];
NSLog(@"after: %@", brokenCharacter);
