Cp437 is a program to emulate an old-style "code page 437" / "IBM-PC" character
set terminal on a modern terminal emulator that uses UTF-8 or similar.
It was written for the purpose of running the BitchX IRC client, which utilises
CP437 line-drawing characters in its default theme and artwork. It should
also be broadly useful for things like viewing CP437 "ANSI art", running
nethack with the IBMgraphics option or running EPIC with scripts that use CP437
