How to convert a NSString to UTF-8 format string in iphone sdk?
提问by Rahul Vyas
I have localization in my app(english,spanish,italian).The client sent me strings files but some characters are strange how do i correct them? i have figured out that the client used Mac OS Roman encoding how do i convert this to utf-8. for example Nürnberg is converted into N√ornberg when client send me now i want to reconvert it.
我在我的应用程序中进行了本地化（英语、西班牙语、意大利语）。客户端向我发送了字符串文件，但有些字符很奇怪，我该如何更正它们？我发现客户端使用了 Mac OS Roman 编码，我该如何将其转换为 utf-8。例如，当客户发送给我时，Nürnberg 被转换为 N√ornberg，现在我想重新转换它。

If you have a properties file with all of the strings... you can load them in and read them with any of these (from NSString's Documentation):
如果你有一个包含所有字符串的属性文件......你可以加载它们并使用其中任何一个读取它们（来自NSString 的文档）：
– initWithBytes:length:encoding:
– initWithBytesNoCopy:length:encoding:freeWhenDone:
– initWithCString:encoding:
– initWithUTF8String:
Here's the list of all possible encodings
这是所有可能的编码列表
enum {
NSASCIIStringEncoding = 1,
NSNEXTSTEPStringEncoding = 2,
NSJapaneseEUCStringEncoding = 3,
NSUTF8StringEncoding = 4, <----- UTF8!
NSISOLatin1StringEncoding = 5,
NSSymbolStringEncoding = 6,
NSNonLossyASCIIStringEncoding = 7,
NSShiftJISStringEncoding = 8,
NSISOLatin2StringEncoding = 9,
NSUnicodeStringEncoding = 10,
NSWindowsCP1251StringEncoding = 11,
NSWindowsCP1252StringEncoding = 12,
NSWindowsCP1253StringEncoding = 13,
NSWindowsCP1254StringEncoding = 14,
NSWindowsCP1250StringEncoding = 15,
NSISO2022JPStringEncoding = 21,
NSMacOSRomanStringEncoding = 30,
NSUTF16StringEncoding = NSUnicodeStringEncoding,
NSUTF16BigEndianStringEncoding = 0x90000100,
NSUTF16LittleEndianStringEncoding = 0x94000100,
NSUTF32StringEncoding = 0x8c000100,
NSUTF32BigEndianStringEncoding = 0x98000100,
NSUTF32LittleEndianStringEncoding = 0x9c000100,
NSProprietaryStringEncoding = 65536
};
