I also have a smartphone. And on one recent trip, as I innocently paraded around the airport before boarding, with my iPhone gently swaying in my shirt pocket as I walked, I found myself irrevocably locked out of my phone for an hour. All that swaying was interpreted by the phone as failed attempts to unlock it. At that moment, all my means of communication went poof, and with them any access to a mobile boarding pass. That would have been super fun if I didn't also have a printed copy.

The forum software has trouble with character encoding, to put it mildly. Handliing encoding can be a kind of a black art, but Unicode has been around for how long now? Like 38 years?

Thank you for pointing out what a GIF actually is, rather than what now goes by that name. Keep history alive!
