small-sized, simple electron device, carried out the problem that Chinese shows and handles.6) all standards of the compatible world because this character library is used the 4Byte ISN, have been reserved more than one hundred million possible space encoders, hold following coinage sign indicating number in the mode of dredging matrix.The correct code position of deciding has solved the needed ranking function of database, makes this character library comprise all spoken and written languages standards of GBK, Unicode, Big5, JIS, KSC sign indicating number and other countries in the world, as Korean, Japanese, Chinese, Tibetan language, seal character or the like.7) but font elasticity convergent-divergent, this character library adopts skeleton vector description, describes the framework size of Chinese character with the stroke notion that meets Chinese, and decides the thickness of font to change with the notion of wieling the pen, font can the elasticity convergent-divergent.8) be convenient to retrieval, character library in the past can only be retrieved with ISN, and purposes is subjected to many restrictions.This character library is based on stroke and parts, and each Chinese character all has the sign indicating number preface of nature and science, can retrieve by component retrieval, concept classification retrieval, initial consonant retrieval, font retrieval and sound shape very easily like this and carry out literal input and inquiry.9) access speed is fast, and this character library is because memory data output is little, and access speed is accelerated greatly in use.According to test, the storage speed of this character library Chinese character in the embedded system applied environment is greater than 1000 word/seconds.10) respect the philology basis, the choice of parts is taken in this character library, according to the definition of dictionary, keeps stroke structure information and text structure information fully as far as possible, has therefore kept the Chinese character information of maximum among ISN.
