Nothing works on non-Latin keyboard layouts

[grishka]

Steps to reproduce:

1. Switch to Russian keyboard layout
2. Try pressing some keys
3. Nothing happens

You shouldn't be using characters typed by keys unless you're accepting text input. Key codes correspond one-to-one to physical keys on the keyboard; characters do not, they're mapped by the operating system depending on user preferences.

Use this tool to see for yourself: event.key you're using changes depending on the active layout, but the numeric key code in event.which stays the same.

Great catch! Accepting Pull Requests for this, otherwise I'll get around to fixing this.
