+> keyName = RL_GetKeyName( int key, int scancode )
+
+This function returns the name of the specified printable key, encoded as UTF-8.
+This is typically the character that key would produce without any modifier keys,
+intended for displaying key bindings to the user. For dead keys, it is typically
+the diacritic it would add to a character.
+
+Do not use this function for text input. You will break text input for many
+languages even if it happens to work for yours.
+
+If the key is KEY_UNKNOWN, the scancode is used to identify the key,
+otherwise the scancode is ignored. If you specify a non-printable key,
+or KEY_UNKNOWN and a scancode that maps to a non-printable key,
+this function returns nil but does not emit an error.

+- Failure return -1
