  • Barcode Encoding and Decoding
    Publication number: 20080048044
    Abstract: Techniques to encode and decode barcodes are described. In an implementation, characters included in content are divided into a plurality of blocks, such that each block is to include compressed or non-compressed characters. An indication is added to a header for each block that specifies whether the block includes compressed or non-compressed characters. Blocks which include non-compressed characters are encoded with a particular codepage. The indication of the non-compressed characters in the header does not reference the particular codepage.
