Question

I’d like to convert GB encoded char * to NSString *:

char *str = ...
size_t len = ...

NSString *s = [[NSString alloc] initWithBytes:str length:len encoding:???];

encoding:NSUTF8StringEncoding is available. I wonder it there an predefined encoding for GB Chinese characters? similar to kCFStringEncodingGB_2312_80, defined in CFStringEncoding.

You can use the CF string encodings with NSString; from Apple’s docs:

Additional encodings are defined in String Programming Guide for Core Foundation (see CFStringEncodingExt.h); these encodings can be used with NSString by first passing the Core Foundation encoding to the CFStringConvertEncodingToNSStringEncoding function.
