The common people considers that, the language and character are used for the information exchanging, in fact they have more important function, they are the very important tools of the human thought. Since the born of humanity, the development of the language and character have experienced 4 stages, the carrier shape and its function in each stage have great enhancement, but, it doesn’t replace and remove the preceding stage, it is compatible with the preceding stage, and coexists with the preceding stage carrier. Moreover the new stage carrier unceasingly is simplifying, and its function is enhancing day by day. The table next shows the development of all stages:

The stage	The carrier	characteristic	new function
body language	body movement	to limit with saw that, written in water	information exchange
spoken language	air vibration	to limit with the ear listens, written in water	Tool of thought
character	two-dimensional graph	to limit with saw, may transmit, can be saved	the promotion thought potency
computer character	electromagnetism condition	Easily massively duplicate, transmitting extremely fast	thought mechanization

The character stage, first it was the stages that character was written with the pen on the paper, in printing age, a great lot of character was printed on paper with the type. This situation however improves the function of the character in storing and spreading abroad, but it lose the function in signature and calligraphy that represent individuality. The mainstream character in information age become invisible state of electromagnetism now, we must use monitor to read it. Computer character is republication of printing character, in other words, it is the method of "storage and code", different type correspond to different code. But the shortcoming of printing character remain as before, future more, reading printing character do not need type, but reading computer character must use whole types(character storage).

Writed character: Pen ——————→article ————→read

Printed character: Type ——————→article ————→read

Computer-char.: storage —→ code —→article ————→read←—storage

If there was only a spell character (example English), it is never mind. But in Chinese, types are various, the problem appeared first, and in internet age, the problem is more and more serious. The requirement of using characters of different countries at same page makes it necessary of using Unicode. Currently the improvement of hardware can easily afford the increasing code length and storage. The problem is that: there are too many character various and they are continually developing, but to collect all of them for ever. Due to the Code Table can't arranged beforehand, and to make sure that character data is not invalidation, the codes that were collected before must be unchangeable, so, in the beginning it is in confusion case.

On the other hand, with the increasing of the number of type in storage, it is more difficult to choose the needed character. Even one-fold Chinese, totally depend on especial input method, although the input methods is various(“ten thousand yards gallop”), there are still some seldom type can't be inputted, must simultaneously use the many kinds of character, is more difficult. The Number of Chinese type about 100000, currently storage has reached to the 80000 types, but also can appear lacks the character, because quantity too big, is easy to make a mistake, has discovered the so-called computer wrong character and the heavy code. We find that the huge Unicode is not a efficiently method, so the Methods IDS,CDL are brought forward. The method construct new character with old character, in principle, it need nothing but only a few etymon, or merely strokes. But the method needs additional structural character and data in appointment position of components. For length of character string for new character is too long, it can not be used as code of character.

The system of Chinese without storage that I developed at 1984 only need 240 etymons without additional character (only few Chinese character needs structural character), the etymon string itself is the code of the Chinese character. In 2003, the demo software on PC Chinese character had been developed; it only used 50 genus strokes, buildup all Chinese characters, including any big dictionary in all no. I think that the way of the solution in computer-Chinese area is building up characters with strokes, and then all character of whole world may be built up with a few element strokes. The first test, 7 element strokes had been used to buildup all ASCII character and many map chart. In fact the 7 element strokes are the 7 subroutine. Character is not a picture; it is made up with single lines (strokes). With the foundation of study about all strokes character of countries and the advanced software and hardware, it will come to truth that we can write all character type with keyboard but not electronic pen. It is the future of Computer-character.

The characters from strokes which do

not included in any big dictionaries

50 genus strokes

Key word: The language and character, Unicode, the encoding, the storage of character type, the computer character

Brief of author: Shi-zhao Zhang, male, born in 04-22-1937, retired high-grade engineer, develop system of Chinese without type storage in 1984, research about that it is correct method to solve Chinese. Web build in 2001, detail refer to http://www.chancezoo.net, http://www.chancezoo.org
