And of course there is a standard 5-bit code that handles most numerics and punctuation as well ("Baudot"), as well as semi-standard mechanisms for 6 "symbol" characters in 32bits ("Radix50"); stuff from the days when mainframes had a whole megabyte of core and space mattered. It's a common enough problem that developing a full custom solution is probably something that should only be done when you're REALLY desparate. (now, decoding radix50 and writing to an ascii LCD on a processor without divide might be a good topic for a coding challenge...)
