Question

I have a file, which I’m reading into an NSString object using stringWithContentsOfFile. It contains Unicode for Japanese characters such as:

\u305b\u3044\u3075\u304f

which I believe is

せいふく

I would like my NSString object to store the string as the latter, but it is storing it as the former.

The thing I don’t quite understand is that when I do this:

NSString *myString = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];

It stores it as: \u305b\u3044\u3075\u304f.

But when I hardcode in the string:

NSString *myString = @"\u305b\u3044\u3075\u304f";

It correctly converts it and stores it as: せいふく

Does stringWIthContentsOfFile escape the Unicode in some way? Any help will be appreciated.

Thanks.

You can try this, dont know how feasible it is..

NSArray *unicodeArray = [stringFromFile componentsSeparatedByString:@"\\u"];
NSMutableString *finalString = [[NSMutableString alloc] initWithString:@""];
for (NSString *unicodeString in unicodeArray) {
    if (![unicodeString isEqualToString:@""]) {
        unichar codeValue;
        [[NSScanner scannerWithString:unicodeString] scanHexInt:&codeValue];
        NSString* betaString = [NSString stringWithCharacters:&codeValue length:1]; 
        [finalString appendString:betaString];
    }
} 
//finalString should have せいふく
