are to save the file as the UTF-16 encoding format, so what is the relationship between the UTF-16 and Unicode, the above content shows the "ff fe" is what it means? Here, we must first make it clear that Unicode is only a character set. It only defines the hexadecimal value of a symbol in Unicode, for example, the Unicode corresponding to "1" in the Chinese character above is 4e00. In addition, it does not do anything else. Why does Unicode not defi

space" (Zero Width, no-break space ), expressed in Fe ff. This is exactly two bytes, and FF is 1 larger than Fe. If the first two bytes of a text file are Fe ff, it indicates that the file adopts the big header mode. If the first two bytes are FF Fe, it indicates that the file adopts the Small Header mode. In Window

Text files usually identify their encoding methods through the first two bytes, but UTF-32 encoding uses the first four bytes to identify their encoding methods. The following are some encoding format identifiers: Encoding Method First few bytes ANSI No format definition Unicode FF fe Unicode big endian Fe FF

address. This address can also be expressed as: 192. 168. 168. 1-Local link addressBy default, the IPv6 protocol of Windows XP configures a local link address for each interface corresponding to the installed Ethernet Adapter. Its prefix is fe80:/64. The last 64 bits of an IPv6 address are called interface identifiers. It is derived from the 48-bit MAC address adapted to the network:Insert the hexadecimal number 0xff-fe into the third and fourth byte

Then there is a question: How does the computer know which encoding to use for a particular file?Defined in the Unicode specification, each file is preceded by a character that represents the encoding sequence, which is named "0-width non-newline space" (ZERO wide no-break space), denoted by Feff. This happens to be two bytes, and FF is 1 larger than FE.If the first two bytes of a te

In the Linux system, there are three commonly used tools for processing text, and grep is one of the Three Musketeers, commonly known as text processing.grep is a powerful text search tool whose full name is: Globally search a Regular Expression and Print. It works by searching and filtering the text based on the given "pattern" of the regular expression engine and printing the matching lines. Therefore, to understand the use of grep we can proceed from two aspects, the use of the 1:grep command
