void	cp437 (bool x=true)
	Enable (or disable) Code Page 437-compatible charset. There was an error in glcdfont.c for the longest time – one character (#176, the 'light shade' block) was missing – this threw off the index of every character that followed it. But a TON of code has been written with the erroneous character indices. By default, the library uses the original 'wrong' behavior and old sketches will still work. Pass 'true' to this function to use correct CP437 character values in your code.
