How to solve golang cmd garbled code

In recent years, Golang (also known as Go) has received more and more attention and favor in the development field. Compared with other programming languages, Golang has higher efficiency and more reliable performance. However, many Golang beginners encounter garbled characters when using Golang's cmd tool, which may be a problem for them. This article will introduce the causes and solutions of Golang cmd garbled characters.

1. Reasons for Golang cmd garbled characters

1. Different system environments

Golang uses UTF-8 encoding format for internal interaction at runtime, not Windows The default GBK encoding format. If the default encoding format of the command line window is not UTF-8, it may cause garbled cmd characters.

2. Different file encoding formats

When the file encoding format is non-UTF-8, if you use Golang to specify the encoding format as UTF-8 for reading, it will also cause Garbled code problem.

3. Unicode Characters

Some Unicode characters may not be displayed correctly directly on some terminals.

2. Solve the Golang cmd garbled problem

1. Modify the terminal encoding format

You can try to modify the terminal encoding format to UTF-8, in Windows system , you can modify it through the following steps: right-click the title bar in the cmd window, select "Properties", select "UTF-8" in the "Code Page" tab, and click "OK".

2. Modify the file encoding format

When your Golang source file encoding format is non-UTF-8, add the following comment to the file header to declare the use of UTF-8 Encoding:

//go:utf-8

3. Handling Unicode characters

can help by converting Unicode characters to their UTF-8 equivalents Golang displays them correctly. This can be achieved using the functions provided by the strconv package.

For example, to convert the Unicode character '⇒' to its UTF-8 equivalent, you can use the following code:

utf8Char := []byte("⇒")
unicodeChar, _ := strconv.Unquote(strings.Replace(strconv.Quote(string(utf8Char)),\\u,\u, -1))
utf8Char = [] byte(unicodeChar)

Summary

Through the introduction of this article, we can find that there are usually three solutions to the Golang cmd garbled problem: modifying the terminal encoding format, modifying the file encoding format, and processing Unicode characters. Appropriate selection of one or more methods can effectively solve this problem. I hope this article can be helpful to people who are new to Golang and provide better solutions for developers.
