I have a NSURLConnection set up, but when the data it gets back is ÆØÅ fx. the response data becomes (null) ?
id String = [[NSString alloc] initWithData:connectionData encoding:NSUTF8StringEncoding];
That's the line saving the response
When you get back the NSData response, you need to convert it to an NSString using appropriate encoding (UTF8 should work for most of the cases). You may try ISO Latin1 encoding if UTF8 is not working.
