how to decode UTF8 string in iphone

Question

I want to decode an UT8 encoded string.

The input string is \"øæ-test-2.txt\"

and after decoding it should become \"øæ-test-2.txt

Answer 1

[NSString stringWithUTF8String:]

Answer 2

I use this one.

NSString *encoded_string = @"ü";
const char *ch = [encoded_string cStringUsingEncoding:NSISOLatin1StringEncoding];
NSString *decode_string = [[NSString alloc]initWithCString:ch encoding:NSUTF8StringEncoding];
NSLog(@"%@",decode_String)
