Returns the last pressed character since previous call to frame function.
Returns the character code.
If no key was pressed or there's no corresponding character, returns 0.
Input_GetChar translates the pressed key code to character considering
the current keyboard states and input locale.
The key states are updated outside user's frame function. So don't use Input_GetChar
in a loop to wait a key to be pressed, this will result in system hang up.
