   - The scancode is hardware dependent, and should not be used by general
     applications.  If no hardware scancode is available, it will be 0.

   - The 'unicode' translated character is only available when character
     translation is enabled by the SDL_EnableUNICODE() API.  If non-zero,
     this is a UNICODE character corresponding to the keypress.  If the
     high 9 bits of the character are 0, then this maps to the equivalent
