- 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
ASCII character:

ch = keysym.unicode & 0x7F;

An international character..
