ASCII is the most dominant criterion in a computer, it is a very high goal indeed.Unicode affects every part of the computer industry, but it may have the greatest impact on operating systems and programming languages. From this point of view, we are already on the road. Windows NT supports Unicode from the bottom level (unfortunately, Windows 98 is only a small subset of Unicode support). The C programming language, which is inherently ANSI-bound, supports Unicode through support for wide-char

When we are doing string processing, if the string processing function cannot implement what we want, we will use regular expressions to help us implement it.Regular Expressions are generally used in the following scenarios: matching, searching, splitting, searching, and replacement. Below we will use PHP and Python respectively for implementation and comparison. PHP Regular Expressions adopt the PCRE style. #1 match Math (and obtain the result)(Note that the matching result must be obtained he

Figure 3 Multi-Channel mode: The network function is only available outside the server. 2.802.1Qbh/802.1BR/VN-Tag 802.1Qbh, as one of the DCB Data Center Protocol families, was proposed by Cisco and has been terminated. Cisco also proposed the 802.1BR protocol. The two have big differences in details, but they are consistent in principle. VN-Tag is Cisco's proprietary technology. It was previously proposed by IEEE and abolished after a period of discussion. It is still used in Cis

Today, I want to use python to call the search results calculated by Baidu box. I can see that the Chinese characters in the URL are encoded in GBK. although I can add Chinese characters directly to the URL, I have also done a python function for converting Simplified Chinese characters to GBK codes, but it is still a little troublesome. I changed it today. , "Wide" is encoded as % B9 % E3. % B9 is called a section encoding, and % E3 is a character encoding (second encoding ). Ideas: Collect Ch

In the book, the Civil War broke out in the small country, the cause of the war is people arguing, whether to eat eggs from the big Head (Big-endian) or from the head (Little-endian) knocked open. For this matter, the war broke out six times, one Emperor gave his life, and the other emperor lost his throne.Therefore, the
