Golang writes Chinese garbled characters

In recent years, Golang has received more and more attention and application in the development field. However, some Gophers (Golang developers) inevitably encounter garbled characters when processing Chinese characters, which brings a lot of trouble to development work. This article will introduce the causes and solutions of Chinese garbled characters in Golang.

The reason why Golang Chinese is garbled

Golang is a strongly typed, statically compiled language, and its character encoding defaults to UTF-8. UTF-8 is a variable-length encoding that can be used to represent all characters in the Unicode character set. However, character encoding is not the only reason for garbled characters in Golang. Here are some other possible reasons:

1. Inconsistent database encoding

When we read from the database When writing data to a file or outputting it to a terminal, there is a high possibility that garbled characters will appear. This is because Golang uses UTF-8 encoding by default, while some databases (such as GB18030-encoded MySQL) use other encoding sets by default, causing characters to be destroyed during transmission.

2. System environment encoding is inconsistent

When Golang runs on some different operating systems (such as Windows or Linux), sometimes there will be encoding inconsistencies. This will cause Chinese characters to render differently on different operating systems.

3. Inconsistent encoding of code files

When writing Golang code, we should pay attention to the encoding format of the code file and ensure that it is consistent with the UTF-8 encoding used by Golang by default . If you are not aware of this, it may cause Chinese characters to appear garbled when compiling or running.

Golang Chinese garbled solution

When dealing with Golang Chinese garbled code, we can take the following solutions.

1. Set character set

Golang provides a simple way to set the character encoding, that is, using the init function in the utf8 package. Just add the following line of code at the beginning of the code:

import _ "unicode/utf8"

In this way, we can ensure that Golang uses UTF-8 encoding correctly.

2. Dealing with garbled characters in the database

When dealing with garbled characters in the database, we should do the following:

a. Confirm the database encoding Type

We need to determine the correct database encoding type, such as UTF-8, GBK, GB2312, etc.

b. Check the data reading code

We need to check whether the code reads the data correctly and match the encoding type in the application with the encoding type in the database.

c. Processing character encoding

If non-UTF-8 encoding is used, we need to use the corresponding encoding library (such as gbk library) to convert the characters to UTF-8 encoding, and then convert them Write to file or output to terminal.

3. Dealing with the garbled problem of the system environment

When dealing with the garbled problem of Golang running on different operating systems, we need to take the following measures:

a . Understand the locale of the operating system

We need to understand the locale of the operating system, especially the default character encoding.

b. Set the language environment of the operating system

If we need to run the Golang program on a different operating system, we need to set the environment variables correctly according to the requirements of the operating system.

4. Handling code file encoding issues

When dealing with code file encoding issues, we can take the following measures:

a. Confirm the code file encoding type

We need to check the encoding type of the code file to ensure that it is consistent with the UTF-8 encoding used by Golang by default.

b. Convert code file encoding type

If we encounter special circumstances (such as needing to share code with other teams), we can use the conversion tool to convert the code file encoding type to UTF-8.

Summary

Golang is a powerful programming language, but it is prone to garbled characters when processing Chinese characters, which may cause trouble for development. In order to avoid this situation from happening, we need to correctly set the encoding, deal with database encoding inconsistencies, deal with garbled system environment issues, and deal with code file encoding issues. Only in this way can we correctly process Chinese characters and make Golang applications more complete.
