This line tells vim to try utf8 and gbk encoding when opening a file. vim only
Before scanning a file, you can determine whether the file is used based on the data in the file.
UTF-8 or gbk encoding. If this line is not specified, vim only uses the current encoding (locale)
To open the file, because your locale is a UTF-8, and the file is gbk, so opening is garbled.
Generally, garbled characters may occur when vim opens a Chinese File. The reason is complicated and it is not so cool. Direct solution
Set fileencoding = gb18030
Set fileencodings = UTF-8, gb18030, UTF-16, big5
Do you want to see the reason for this setting? Continue. The following is widely used in the Internet
The encoding in vim is mainly related to three parameters: enc (encoding), fenc (fileencoding), and fencs (fileencodings)
Fenc indicates the encoding of the current file, that is, a file correctly displayed in vim (provided that your system environment matches your enc settings ), you can change fenc and then w to save the file into different encodings. For example, I: set fenc = UTF-8 and then: w will save the file as UTF-8, and: set fenc = gb18030 and then: w will save the file as gb18030. This value does not matter whether the file can be correctly decoded when it is opened.
Fencs is a list of guesses used to decode a file when it is opened. File encoding is not correct, so vim can only guess the file encoding. For example, the setting in my vimrc is
Set fileencodings = UTF-8, gb18030, UTF-16, big5
Therefore, each time I open a file in vim, I first try to use UTF-8 for decoding. If an error occurs when I use UTF-8 for decoding, the so-called error means that UTF-8 cannot be correctly decoded somewhere ), then, use gb18030 to re-decode the code from the beginning. if gb18030 is wrong (note that gb18030 is not a UTF-8-like rule encoding, the so-called error is that a specific encoding has no meaningful words, for example 0), try to use the UTF-16, still try to use big5 error. In this case, if there is no error in the decoding process from the beginning to the end, vim considers the file to be encoded and will not try again. At this time, the fenc value will be set as the final encoding value used by vim. you can use: set fenc? To view the specific information.
Of course, this may also cause errors. for example, if your file is gb18030 encoded, but in fact only one or two characters are Chinese, then they may also be decoded by UTF-8, this file will be mistakenly identified as UTF-8, resulting in incorrect decoding.
As for enc, its function is basically display. No matter what encoding the final file is, vim will convert it to the current system encoding for processing, so that it can be correctly displayed in the current system, therefore, enc does this. In windows, the default value of enc is cp936, which is the default encoding of Chinese windows. Therefore, enc does not need to be changed. In linux, as your system locale may be set to zh_CN.gb18030 or zh_CN.utf-8, your enc should be set to gb18030 or UTF-8 (or gbk ).
Finally, let's talk about the default encoding of the new empty file. It seems that the first encoding in fencs will be used as the default encoding of the new file. However, there is a problem here, that is, the order of fencs has a lot to do with the decoding success rate. according to my experience, the success rate of UTF-8 is higher than that of gb18030, if I create a new file and want it to be gb18030 encoded by default, what should I do? One method is to set fenc = gb18030 after each file creation, but I found that setting fenc = gb18030 in vimrc can also achieve this effect.
In addition, some people have proposed this method in the ubuntu Chinese forum and configured it directly.
Paste all the code directly to the terminal to run it!
