NSURL with special characters

Question

How can I encode this url to be displayed in a UIWebview:

http://de.wikipedia.org/?search=Bevölkerungsentwicklung

I tried:

-stringByAddingPer

I found also that for some North European characters, NSISOLatin1StringEncoding fits better. This one gives me a better result

- (void) testEncoding {
    NSString * urlString = @"http://example/path/fileName_blå.pdf";
    urlString = [urlString stringByAddingPercentEscapesUsingEncoding:NSISOLatin1StringEncoding];
    NSURL * url = [NSURL URLWithString:urlString];
    NSLog(@"URL: %@", url);
}
