> avoid backticks in passwords

I learned that lesson a different way: When I had a Windows phone my email password had a backtick, and the only way to enter it on the phone was to long-press the apostrophe, pick backtick from the three or four apostrophe variants that appeared, and pray I didn't fat-finger it and enter the wrong character. In general, there are just some second class citizen characters you should always avoid, because you never know how hard they're going to be to enter when you're on a phone or a kiosk or whatever. (Tilde, I'm looking at you, too.)
