C How to read a text file 50

Just specify the appropriate encoding methodThe .net class library automatically recognizes Chinese or English (single or double byte).

It is recommended to use this to indicate the default encoding scheme of the operating system, and it is best not to specify the encoding scheme for your own assertions, as you may be dealing with various versions of the Windows operating system.

Generally speaking, a single byte is an ASCII code, and such encoding ranges from 0 to 127 If converted to binary, the highest bit is always zero.

For example, the binary of 127 of the ASC code is: 01111111

In a double-byte encoding scheme, the highest bit is always 1

For example, the binary of the word "中" is: 11010110 11010000

Therefore, the text software is to correctly identify the "single word" and "double word" through the feature I mentioned above, in addition to preventing the problem of "bad words", that is, a large section of text will not be read correctly because of a bad word.

PS: You can use the UltraEdit "binary" way to view, use the hexadecimal display in Ultraedit, and use the Windows calculator to convert the binary display mode, so it's intuitive (look at -> scientific, and then you can switch back and forth between hexadecimal and binary).
