Currently when trying to use the right-shift on the pt-br layout
it prints a "?" on key-down on top of applying the shift modifier.
This patch removes the unwanted "?".
Adds /?° key (scancode 115).
Shift + 6 now maps to ¨ instead of space.
AltGr + (1-6) now map to ¹²³£¢¬.
AltGr + = now maps to §.
AltGr + [ now maps to ª.
AltGr + ] now maps to º.
AltGr + q now maps to /.
AltGr + w now maps to ?.
AltGr + e now maps to °.
AltGr + c now maps to ₢.
