//My Memo for UTF8 code in Objective-C
// How to use UTF8 中文字串 在 iOS

const static char *Word[] = {

    "一乙",

    "二力刀乃人匕又入了卜几丁" 

}

NSString *stringFromUTFString ;

stringFromUTFString = [[NSString alloc] initWithUTF8String:Word[1] ]; // load code to NSString

NSLog(@"%d" , stringFromUTFString.length  ); // 結果是 12 

    

for (int i = 0; i < stringFromUTFString.length; i++) {

        NSRange  strRange = NSMakeRange(i, 1); // i = index , 1 = range length

        NSString *subStr = [stringFromUTFString  substringWithRange:strRange];

        // subStr 結果是 @"二力刀乃人匕又入了卜几丁" one by one output     

        NSLog(@"%@" , subStr  );
