endcoding을 통한 string 생성

char *utf8String = /* assume this exists */ ;

NSString *stringFromUTFString =

[[NSString alloc] initWithUTF8String:utf8String];

char *macOSRomanEncodedString = /* assume this exists */ ;

NSString *stringFromMORString =

            [[NSString alloc] initWithCString:macOSRomanEncodedString

                              encoding:NSMacOSRomanStringEncoding];

NSData *shiftJISData =  /* assume this exists */ ;

NSString *stringFromShiftJISData =

            [[NSString alloc] initWithData:shiftJISData

                              encoding:NSShiftJISStringEncoding];

UTF-8로 인코딩된 NSString과 ASCII 사이의 변환

unichar ellipsis = 0x2026;

NSString *theString =

[NSString stringWithFormat:@"To be continued%C", ellipsis];

NSData *asciiData =

[theString dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

NSString *asciiString =

[[NSString alloc] initWithData:asciiData encoding:NSASCIIStringEncoding];

// NSLog를 통한 결과

// Original: To be continued… (length 16)

// Converted: To be continued... (length 18)
