1. Run the game.
2. Attempt to enter "@", with a UK keyboard (standard version) http://puu.sh/3kFf8.png

I found this whilst trying to enter my email, it seems that the program itself is using a US keyboard (But my keyboard settings never change in Windows..) as I could enter an @ symbol with shift + 2, which is " for us in the UK.
Repeatability: 100% on the title screen. Also works with " ' " (the same key, sans shift modifier.)
I repeated the same action whilst picking the campaign, and came back to this window (Running in windowed mode), and when I returned to SotS, it had stopped responding. Not sure if it's because I left that console open for a while (A couple of minutes?)
This is with the Steam version, so I posted it here.
Amusing anecdote: I found this bug/issue before I even learned General Akamoto's name, which made registering here moderately amusing xD;
