But it doesn't work, so please give help me out?.

Answer 1

Either what you have is binary data, or you have a string in some encoding that's not UTF-8. Assuming it's the latter, you need to figure out what that encoding is, which is entirely dependent on the data, what it is, and where it came from.

Answer 2

TESTED CODE: 100 % WORKS

NSLocale *locale = [[NSLocale alloc] initWithLocaleIdentifier:@"en-US"];

NSString *input = @"ı: ürse kün";


NSString *folded = [input stringByFoldingWithOptions:NSDiacriticInsensitiveSearch locale:locale];


NSLog(@"resulted String is - %@",folded);

OUTPUT:

    resulted String is - A±: A¼rse kA¼n

OR

NSLocale *locale = [[NSLocale alloc] initWithLocaleIdentifier:@"en-US"];

NSString *input = @"ı: ürse kün vijay 12344";

input = [input decomposedStringWithCompatibilityMapping];


NSString *output=[input stringByTrimmingCharactersInSet:[[NSCharacterSet characterSetWithCharactersInString:@"abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLKMNOPQRSTUVWXYZ0123456789"] invertedSet]];


NSString *folded = [output stringByFoldingWithOptions:NSDiacriticInsensitiveSearch locale:locale];


NSLog(@"resulted String is :%@",folded);

OUTPUT:

resulted String is :A±: A1⁄4rse kA1⁄4n vijay 12344
