What is the most efficient way to encode an arbitrary GUID into readable ASCII (33-127)?

Question

The standard string representation of GUID takes about 36 characters. Which is very nice, but also really wasteful. I am wondering, how to encode it in the shortest possible

Answer 1

Assuming that all of your GUIDs are being generated by the same algorithm, you can save 4 bits by not encoding the algorithm nibble, before applying any other encoding :-|
