How to prepare an NSURL from an NSString continaing international characters?

Question

I have to access a web server using a GET with international characters (Hebrew in my case but could be anything). So I make an NSString just fine

Answer 1

+ (NSURL*) URLWithStringWithSpecialChars:(NSString *)sURL
{
    NSURL *url = [NSURL URLWithString:sURL];
    if(url == nil)
        return [NSURL URLWithString:[sURL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
    else
        return url;
}

calling this function instead of URLWithString: should ensure that a valid NSURL is always returned (instead of nil when needed)
