And just to add in one more bit about why it's important to separate the text from the binary header, -initWithData:encoding: "[r]eturns nil if the initialization fails for some reason (for example if data does not represent valid data for encoding)." (That is from the NSString docs.)

In all probability, the header is a fixed length and you can just skip that part of the data. Either way, if this is meant for more than a casual, one-off, in-house app, you'll have to find a more reliable technique.
