How to deal with garbled characters displayed on the Linux terminal

Linux system is one of the widely used operating systems, which provides powerful command line tools to complete various tasks. However, sometimes garbled characters appear when using the Linux terminal, causing trouble to users. This article will introduce how to deal with garbled display on the Linux terminal and provide specific code examples.

1. Reasons for garbled code display

Garbled code display is usually caused by a mismatch between the terminal and text encoding. If the encoding settings of the terminal are inconsistent with the encoding of the text file, garbled characters will appear. Common garbled situations include Chinese characters being displayed as a bunch of garbled characters, special symbols being displayed abnormally, etc.

2. Solution

2.1 Check the current terminal encoding

First, we need to check the encoding settings of the current terminal. You can view it through the following command:

echo $LANG

This command will output the encoding settings of the current terminal. Typically, UTF-8 is the more common encoding.

2.2 Modify the terminal encoding

If the terminal encoding setting is incorrect, we can solve the garbled code problem by modifying the terminal configuration. Common terminal programs such as gnome-terminal, konsole, xterm, etc. have their own encoding setting options.

Taking gnome-terminal as an example, you can open the terminal configuration menu through the following command:

gnome-terminal --preferences

In the menu Find the encoding option and set the encoding to UTF-8, which is consistent with the text file encoding, to solve the problem of garbled code display.

2.3 Convert text file encoding

If the encoding setting of the terminal is correct, but the encoding of the opened text file does not match, garbled characters will also be displayed. You can use the iconv command to convert the encoding of a text file. For example, to convert a file from GBK to UTF-8, you can use the following command:

iconv -f gbk -t utf-8 input.txt > output.txt

This way you can The encoding of the text file is converted to an encoding that matches the terminal to solve the problem of garbled code display.

2.4 Use the locale command

locale command to view and set the system's region and locale. You can unify the encoding of terminal and text files by setting the system locale.

3. Summary

Through the above methods, we can solve the problem of garbled code display on the Linux terminal. First check the encoding settings of the terminal and text files, and then solve the garbled display situation by modifying the terminal configuration, converting the text file encoding, or setting the system locale. With the correct encoding settings, we can display various characters and text content normally and improve work efficiency.

We hope that the above methods can help users who encounter garbled characters in Linux terminals and enable them to use the Linux system more smoothly.
