Since it's early in the process, I figured I'd try the wireless since it is convenient and see how it went. As a result, a potential issue/bug was dicovered so in the long run it's a win. If I absolutely needed the update to finish a session or something then yes, pulling the unit from the rack and cabling it up would have been the process.
Yes, thanks for reporting it. This will be fixed in the next software update – you'll be able to enter all the characters on a standard keyboard. I am asking myself if this goes far enough for international users, but we will address that if it comes up.
