Chapter 747 Addition and Subtraction
“In my opinion, the new font library needs to meet several standards.”
“The first is that the code bits must be broad. My opinion is that the code point should be 200,000 as the benchmark;"
"The second is compatibility with GB2312 and GB13000, which requires a complete, clear and clear code mapping table to achieve free conversion."
"The third is to make clear and detailed regulations on the use of standard user-defined areas and standard reserved areas. It allows users to use the thirteen strokes and Chinese character reference components provided by the font library to create their own custom areas. At the same time, strict standards and usage methods must be formulated for these newly added Chinese characters, and they must be upgraded in a timely manner to load the approved Chinese characters into the standard reserved area.”
"This allows us to work together, which not only reduces our workload, but also gives users the opportunity to participate in the construction of the font."
No one here has thought of this, and now I bring it up to Zhou Zhiyi, everyone Everyone's eyes lit up, this guy's mind is really smart!
“The last one is, of course, mandatory standards. We need a strongly binding standard specification to increase visibility.”
“Mandatory standards have the highest visibility. If the end users of Chinese software Knowing that we have developed an optimal Chinese character standard, we will definitely require software developers to implement it.”
“In turn, software developers have to pay attention to the standard and implement this standard to improve it. own competitiveness.”
"Is this standard...too high?" Mai Mingchuan scratched his forehead: "I estimate that 99% of users will not use it."
"I just said, If you don’t need the complete collection, you can choose subsets at different levels.” Zhou Zhi said: “But this does not mean that the complete collection is not enough. It should be."
"Director Mai, as far as I know, the logic algorithms used by electronic computers, including design concepts, are actually mature subjects decades or even one or two hundred years ago, until humans invented the transistor. Only after technological breakthroughs are achieved can mathematical results from mature disciplines be applied to On the integrated circuit, today's information industry was formed."
"Frege, Russell and Boole, they did not say that their mathematical logic research standards were too high in the 19th century. We have to wait until the 21st century when information technology sprouts. Isn’t it too late to let future generations do research? "
"Hahahahaha..." Mai Mingchuan laughed: "Classmate Zhou Zhi is using the spear of the son to attack the shield of the son. He has learned good logic. Are you interested in studying in our computer department? ? This is the most scarce and urgently needed major in the country! ”
"Don't think about it." Mr. Gu waved his hand: "My first choice is my Chinese department, followed by the history department, and then the philosophy department. He is a liberal arts student."
"A liberal arts student?" This is the next round. When I arrived at Mai Mingchuan, I was surprised: "Arts students have Such rigorous logical thinking?"
"Director Mai is looking down on us," Zhou Zhi said with a smile: "Our ancient prose has a set of repeated grammar, which in itself shows that we have a strict set of rules. thinking logic ed. ”
“Our ancient famous schools, the Legalist school, and the Politician school are all masters of using this set of thinking. Just because we have not listed it as a separate subject and written a monograph does not mean that represent us Without this knowledge, no one would have studied it.”
“You are going too far,” Mr. Gu said with a smile, “But I think the idea is good, and our goal can indeed be set higher. ”
"Mr. Gu, you don't know how expensive internal and external storage is now," Mai Mingchuan said: "The font library needs to be transferred into the memory so that it can be used quickly and easily. Today's computer systems generally only have eight megabytes of memory, and the operating system is loaded , especially the current visualization system, which consumes a lot of memory There is not much left for application.”
“With the advancement of technology, these can always be solved,” Gu Youwen said: “As Zhuzi said, we can first. Have ideas, theories, and reserves.”
After saying that, he patted the Heap of manuscripts: "With these things, it is completely feasible to standardize them first and then apply them!" "Actually, this is the same as the platinum weights and measures in the Bureau of Standards and Measures," Tenzin said with a smile: "When the standards are formulated, we might as well It’s just high. When it comes to application, we can adjust measures to local conditions.”

“In fact, as long as there are standard dot matrix characters, it is not difficult to expand the character library.” Li Hongjiang was a little excited: “Because no matter whether the Chinese characters are complex or simple, traditional or simplified, their basic strokes and The radical structure is the same.”
"That is to say, we can completely use the stroke coupling technology of GB2312 and GB13000. With dot matrix fonts, we can create four basic fonts: Hei, Song, Fang Song, and Kai."
"Yes, this This is the advantage of our Chinese characters." Zhou Zhi said: "We. On the manuscript, the other three fonts other than dotted characters are actually used for correction by Professor Li. If Professor Li thinks there are no problems, I will ask my classmates to write dotted characters specifically from now on. "
"Elbow, your classmate is also a high school student? Then is he interested in coming to our calculations? "Engineer department?"
"Well, my classmate is from a hydropower school, a vocational high school, and has already graduated and started working at Manzhou Electric Power Company." Zhou Zhi said, "By the way, I have another request. Professor Li, if our manuscript is used, among the researchers, I hope that my classmate’s name will be added to it.”
“Now all that’s left is to develop the scanning program and coding.” Li Hongjiang tapped his chin with two fingers, lost in thought: “It’s still a matter of time. It would be best if we could do it before the launch of GB13000. We convinced The standards committee has a better chance..."
"Actually, I have another idea," Zhou Zhi said.
"You have your say." Mai Mingchuan is now looking at the boy with a hundred eyes. In theory, this boy has opened everyone's minds and has also done the most difficult work. Now All that remains is the issue of warehousing and encoding.
As for these two, the country already had considerable experience when compiling GB2312 and GB13000.
“In fact, we can also reverse the operation.”
“What reverse operation?”
"Develop a text recognition software." Zhou Zhi said: "A software that can recognize Chinese characters, process the Chinese characters into dot matrix characters, and then automatically assign codes to the Chinese characters according to certain rules such as radicals and put them into the character library code bits software."
"Do you have any design ideas?" Li Hongjiang became interested. Chinese recognition is a good thing.
“The design idea of this program is this.” Zhou Zhi said: “Because Chinese characters themselves have certain organizational rules, mainly square characters, we can use these rules to scan it and analyze it. . ”
“Theoretically, the position of the center of gravity, the retraction and expansion of the central palace and other characteristics of each Chinese character, especially the printed version, are the same in a classic. We can Through extensive sampling, the average values are obtained, and then these average values are used as font design parameters for Chinese characters and assigned to existing dot matrix characters to produce the same font as the classics."
"If we think about it the other way around, we can. It is believed that every text in a classic is a graphic calculated by a font algorithm, and this graphic itself fully covers all the boundaries of its dot matrix characters.”
"If we decouple it according to the previously swept parameters, that is, do subtraction, theoretically it is possible to reduce text graphics into standard dot matrix characters."
