Not able to decode the encoded unicode string

Question

i am not able to decode this encoded string to its unicode value:- %5Cu20A8

NSData *unicodedStringData =
    [@"%5Cu20A8" dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:NO];
    NSString *stringValue =
    [[NSString alloc] initWithData:unicodedStringData encoding:NSUTF8StringEncoding];

I have tried NSASCIIStringEncoding and NSUnicodeStringEncoding as well but it doesnt work.

Answer 1

This Worked:-

NSString *unicodedString = [[dictMain objectForKey:@"currency"] stringByRemovingPercentEncoding];

NSData *unicodedStringData = [unicodedString dataUsingEncoding:NSUTF8StringEncoding];

NSString *currencyUnicode = [[NSString alloc] initWithData:unicodedStringData encoding:NSNonLossyASCIIStringEncoding];

Just removing percent escapes before decoding the string.

Answer 2

Just improved Ashish's answer

NSString *unicodedString = [@"%5Cu20A8" stringByRemovingPercentEncoding];

NSData *unicodedStringData = [unicodedString dataUsingEncoding:NSUTF8StringEncoding];

NSString *currencyUnicode = [[NSString alloc] initWithData:unicodedStringData encoding:NSNonLossyASCIIStringEncoding];
NSLog(@"%@",currencyUnicode);

Output - ₨
