windows10 ftp 451 No mapping for the unicode character exists in the target multi-byte code page
When using the company's ftp server, there is a problem with uploading the folder, but it cannot always be reproduced. The problem package error is as follows:
451 No mapping for the unicode character exists in the target multi-byte code page
The reason for this problem is that there are both English files and Chinese-named files in the folder, which leads to errors in windows recognition.
Solution:
1. Modify the server configuration
And it is indeed server’s configuration issue. By changing the Allow UTF8 fro True to False in the Advanced Setting
This is a problem that the server's configuration is inconsistent with the client's encoding. In the advanced settings, the problem can be solved by changing the allowable UTF8 to true or false. My opening here is true, and there is no problem after changing it to false.
2. Modify the client configuration (take FileZilla as an example)
- Start FileZilla.
- This article uses FileZilla as an example, and the operation methods of other FTP clients are similar.
- On the top menu bar, choose File > Site Manager.
- In the selection record area of the pop-up Site Manager dialog box, left-click the site that reported the error.
- Click the Character Set tab, select Mandatory UTF-8 (U), and click Connect.
deeper reason
The underlying reason for this problem is that
the Windows system in China uses Simplified Chinese encoding.
Enter the following command in cmd to view the default encoding set of the system:
C:\Users\Administrator>chcp

My active codepage is 936 which means "China - Simplified Chinese (GB2312)"
Explanation: The code page is an alias of "character set encoding", and some people call it "internal code table".
