Couldn't find a discussion on the original Getting Started w/ Raspberry Pi article (http://www.howtogeek.com/138281/the-htg-guide-to-getting-started-with-raspberry-pi/) so figured I'd add here in case someone searches for problem/solution I discovered.
As I'm working on command line the wrong symbols were being echo'ing. ~ and @ and # would show up as other symbols.
I figured out my Pi came defaulted to UK keyboard. From command line ran sudo raspi-config, went into Internationalisation Options, Change Keyboard Layout, picked my keyboard, then selected English (US). Saved, rebooted, now everything is hunky dory
