Without resorting to core foundation:

#import 

int main (int argc, const char *argv[]) {
   NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

   NSString *unicodeCharacters = @"àáảãạâầấẩẫậăằắẳẵặèéẻẽẹêềếểễệđìíỉĩịòóỏõọôồốổỗộơờớởỡợùúủũụưừứửữựỳýỷỹỵÀÁẢÃẠÂẦẤẨẪẬĂẰẮẲẴẶÈÉẺẼẸÊỀẾỂỄỆĐÌÍỈĨỊÒÓỎÕỌÔỒỐỔỖỘƠỜỚỞỠỢÙÚỦŨỤƯỪỨỬỮỰỲÝỶỸỴÂĂĐÔƠƯ";

   NSString *decomposed = [unicodeCharacters decomposedStringWithCanonicalMapping];
   NSLocale *usLocale = [[[NSLocale alloc] initWithLocaleIdentifier:@"en_US"] autorelease];

   NSString *cleaned = [decomposed stringByFoldingWithOptions:NSDiacriticInsensitiveSearch locale:usLocale];
   cleaned = [cleaned stringByReplacingOccurrencesOfString:@"đ" withString:@"d"];
   cleaned = [cleaned stringByReplacingOccurrencesOfString:@"Đ" withString:@"D"];
   NSLog (@"%@", cleaned);

   [pool drain];
   return 0;
}
