Abstract
A data coding system is arranged such that character font data is compressed in a unit of 4-bit in a form of a bit string with a compression width of 4-bit in the Huffman coding system. The data coding system employs a code structure in the Huffman coding system for respectively converting three bit strings selected in order from that of the highest appearance frequency in a unit of 4-bit in the character font data into the compressed codes expressed using not more than 3 bits. The described system permits a significantly improved compression rate of the character font data into respective compressed codes.
