What is the solution to the occurrence of Chinese garbled code in Go under CMD? I believe many inexperienced people are at a loss about it. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

1. The error message is as follows

2. Cause analysis.

Because the coding of Go is UTF-8, and the active page of CMD is cp936 (GBK), garbled code is generated. In Chinese Windows systems, if a text file is UTF-8 encoded, the contents of the file will not be displayed correctly in the CMD.exe command line window (the so-called DOS window). By default, the code page used in the command line window is Chinese or American, that is, the code is a Chinese character set or an English character set.

3. Solution

Golang defaults to utf8 when dealing with Chinese, and garbled codes will occur when other characters such as GBK are encountered. The transcoding under the official golang.org/x/text/encoding/simplifiedchinese package of golang is described here.
