+After https://github.com/termux/termux-x11/pull/768, Termux:X11 now supports
+Backspace Key (in both hardware and software keyboards), but this would not work
+in certain specific games like Luanti and SuperTux (neither in Termux:X11 nor in
+other X11 server implementations like the $PREFIX/bin/Xvnc program from the
+tigervnc package) because there is something bugged about their keymaps when
+they are built for Termux that causes the registered keyboard inputs to be
+scrambled to incorrect values, specifically regarding the Backspace, Space and 9
+keys.
+
+The true root cause shared by both games is not yet known.
+This patch works around the problem as it manifests in Luanti.
+
+- Globally (to Luanti) swaps the internal keycodes of KEY_SPACE and KEY_KEY_9
+  to produce the desired practical default result for both software and hardware keyboards.
+  In-game there IS a GUI that allows rebinding the keys without this patch, but since
+  the default behavior is always incorrect, swapping them at build-time with a patch
+  delivers a more convenient workaround to users than having to always reconfigure these
+  two keybinds manually.
+
+- Globally (to Luanti) replaces the internal keycode of KEY_BACK with 0x9E, which is a value
+  that has an unknown origination point, but is now detected by debuggers inside the scancode
+  handling functions of Luanti's code after Backspace support was added to Termux:X11,
+  for both hardware and software keyboards
+
+- No other keys are currently known to be affected by these problems
