Split-iterated algorithm for 2D bar code encoding of the GB18030-character-set-based Chinese ideograms
Renjie Zhang · Journal of Computer Applications · 2007
It is very important for the wide use of 2D bar codes in certificates to encode the Chinese ideograms that are rarely seen and used in social life while more people would like to have them in the name to show its uniqueness. GB18030—2005 character set makes it possible to solve such a question with nearly 27000 Characters included. The encoding regulations for Chinese ideograms in GB18030 were analyzed here and then the 2D bar code PDF417 encoding method of the mixed information of Chinese ideograms with ASCII characters was put forward. A special byte-compression method named split-iterated algorithm which could save memory without loss of encoding efficiency and could be realized on 16-bit programming tools was introduced here too. An example was given in this paper to illustrate the whole encoding process.
