independent organizations that attempt to create a single character set, the Unified Code Alliance of the International Organization for Standardization (ISO) and the multi-language software manufacturer. The former developed the ISO/IEC 10646 project, the latter developed by the unified Code project. Therefore, different standards were originally developed.
Around 1991, participants in two projects realized that the world did not need two incompatible character sets. As a result, they began

greater than 127 ). The preceding two bytes are used to represent a Chinese character. In practice, they are called dual-byte (that is, DBCS:Double-byte character set). In contrast, an English character code is called a single-byte sbcs (single-byte characterSet ).
Although the dual-byte (DBCS) is sufficient to solve the mixed use of Chinese and English characters, it is very troublesome for different character systems to undergo bytecode conversion. For example, Chinese and English, Japanese,

However, it is said that the efficiency is "amazing", so it is still worth it, however, it is not ruled out that the GPU will be used out faster in N years. Woo shadow ing is similar in principle.

The horizontal axis is the Time axis and the vertical axis is the Quality axis;
Time = 2Indicates On Time (the code is completed On Time );
Time = 6Delay (Code Extension completed );
Quality = 2Terrible (bad code );
Quality = 6Not bad (code that is okay );
Quality = 8Indicates Excellence (excellent Code );
Conclusion: "bad code On Time, good code Delay ."
Ps: Actually, I just want to express one point of view: it takes time to make the best way.

interaction between the Presenter and the Model is clear. It only shows that the interaction between the one-way call View and the Presenter of the Model is the core of the entire MVP, whether MVP's original intention for separation of concerns can be reflected in specific applications depends largely on whether the interaction between the two is correct. MVP members are divided into PV (Passive View) and SC (SuperVising Controller) modes based on the interaction mode between View and Presenter
bytes to represent a Chinese character. Therefore, it can theoretically represent a maximum of 256x256 = 65536 characters.
The issue of Chinese encoding needs to be discussed in a specific article. This note does not cover this issue. It is only pointed out that although multiple bytes are used to represent a symbol, the Chinese character encoding of the GB class has nothing to do with the Unicode and UTF-8 of the subsequent text.

is: F = {SnO → classno, courseno → credit }, there are two relationship modes: SC1 (SNO, classno) and SC2 (courseno, credit). This decomposition maintains function dependencies, but it does not have lossless connectivity. therefore, a break-down of the relational model may maintain the function dependency, which may be non-destructive or non-destructive. (2) if the decomposition is required to have lossless connectivity, the mode decomposition
