问题描述
我将字符串转换成可读取的问题。我正在使用
I'm having problems converting the string to something readable . I'm using
NSString *substring = [NSString stringWithUTF8String:[symbol.data cStringUsingEncoding:NSUTF8StringEncoding]];
但是我无法将\U7ab6\U51b1转换为'
but I can't convert \U7ab6\U51b1 into '
它显示为窭冱这是我不想要的，它应该显示为'。任何人都可以帮助我吗？
It shows as 窶冱 which is what I don't want, it should show as an '. Can anyone help me?
推荐答案
这是字符U + 2019 RIGHT SINGLE QUOTATION MARK。
That's character U+2019 RIGHT SINGLE QUOTATION MARK.
发生了什么事你已经以UTF-8编码提交给您的字符序列的，以字节为单位出现：
What has happened is you've had the character sequence ’s submitted to you, in the UTF-8 encoding, which comes out as bytes:
’ s
E2 80 99 73
该字节序列然后，错误地将其解释为在Windows代码页932（日语;或多或少Shift-JIS）中编码：
That byte sequence has then, incorrectly, been interpreted as if it were encoded in Windows code page 932 (Japanese; more or less Shift-JIS):
E2 80 99 73
窶 冱
所以在这个特殊情况下，你可以通过首先将字符编码为cp932字节，然后使用UTF-8将这些字节解码为字符来恢复的字符串。
So in this one particular case, you could recover the ’s string by firstly encoding the characters into cp932 bytes, and then decoding those bytes back to characters using UTF-8.
然而，这不会解决你真正的问题，这是字符串被读入公司首先是正确的。在这种情况下，您得到窭冱，因为编码的所产生的UTF-8字节序列也是有效的Shift-JIS字节序列。但是您可能会遇到的所有可能的UTF-8字节序列都不是这样。许多其他字符将被无法解释。
However, this will not solve your real problem, which is that the strings were read in incorrectly in the first place. You got 窶冱 in this case because the UTF-8 byte sequence resulting from encoding ’s happened also to be a valid Shift-JIS byte sequence. But that won't be the case for all possible UTF-8 byte sequences you might get. Many other characters will be unrecoverably mangled.
您需要查找字节读取到系统中并将其解码为Shift-JIS，并将其修正为使用UTF-8
You need to find where bytes are being read into the system and decoded as Shift-JIS, and fix that to use UTF-8 instead.
