Varicode

Varicode is a huffman code for use in PSK31. It supports all ASCII characters, but the characters used most frequently have shorter codes. The space between characters is indicated by a 00 sequence. Origionaly created for speeding up real-time keyboard-to-keyboard exchanges over low bandwidth links, it is a very useful format to shrink text files. Varicode is freely available.
