Abstract
The reading and decoding of two-dimensional bar codes and other dataforms are simplified and field loading of different data character sets is enabled. Dynamic loading of new data character sets fully or partially superseding a factory installed default character set correlation listing is enabled by use of loadable correlation listings keyed to foreign language characters, symbols, words or phrases relevant to particular applications. The loadable correlation listings can be encoded into a two-dimensional bar code and loaded via a reading of the bar code by the bar code reader. Two or more correlation listings may be loaded into a bar code reader, with one of the correlation listings selected for decoding a particular bar code.
