Abstract
A system and method for compressing and decompressing multiple types of character data. The system and method employ multiple encoding tables, each designed for encoding a subset of character data, such as numeric data, uppercase letters, lowercase letters, Latin, or UNICODE data, to perform compressions and decompression of character data, and. The compression solution also provides for the creation of new encoding tables on the fly, and accommodates the compression of lengthy character streams using multiple different general compression algorithms, automatically choosing a suitable general compression algorithm for specific input data.
