How to solve Chinese garbled characters in Linux

The Linux Chinese garbled problem is a common problem when using Chinese character sets and encodings. Garbled characters may be caused by incorrect file encoding settings, system locale not being installed or set, and terminal display configuration errors, etc. This article will introduce several common workarounds and provide specific code examples.

1. Check the file encoding settings

1. Use the file command to view the file encoding
   Use the file command in the terminal to view the encoding of the file:

   file -i filename

   If there is "charset=xxxx" information in the output, it means that the file encoding has been set correctly.

2. Modify file encoding
   If the file encoding setting is incorrect, you can use the iconv command to convert the file to the correct encoding:

   iconv -f old_charset -t new_charset filename -o new_filename

   where old_charset is the current file encoding , new_charset is the correct encoding, filename is the file name to be converted, and new_filename is the converted file name.

3. Modify the default file encoding
   In some cases, it is necessary to modify the system default file encoding settings. First, back up the system's default locale file:

   sudo cp /etc/locale.gen /etc/locale.gen.bak

   Then use a text editor to open the locale file and uncomment the encoding line that needs to be set:

   sudo nano /etc/locale.gen

   After saving the file and exiting the editor, run The following command makes the setting take effect:

   sudo locale-gen

   2. Install and set the system language environment

4. Check whether the system language environment is installed
   Use the locale command to view the current system language environment Locale:

   locale

   If no information similar to "LANG=zh_CN.UTF-8" is output, it means that the system locale is not installed.

5. Install the system locale
   The following command will install the Chinese locale:

   sudo apt-get install language-pack-zh-hans language-pack-zh-hans-base

6. Set the system locale
   Use locale- The gen command generates the locale setting of the Chinese environment:

   sudo locale-gen zh_CN.UTF-8

   Then sets LANG to the Chinese encoding:

   sudo update-locale LANG=zh_CN.UTF-8

   After restarting the system, the system's locale setting will take effect.

3. Adjust the terminal display configuration

1. Modify the terminal configuration file
   Use a text editor to open the terminal configuration file:

   nano ~/.bashrc

   Add the following content at the end of the file:

   export LC_ALL=zh_CN.UTF-8
   export LANG=zh_CN.UTF-8

   After saving the file and exiting the editor, run the following command to make the settings take effect:

   source ~/.bashrc

2. Set terminal font
   Open the terminal Window, right-click and select "Preferences", select the terminal configuration file used in the "Profiles" tab, click "Edit", and select the appropriate font settings in the "General" tab.

To sum up, this article introduces several methods to solve the problem of Chinese garbled characters in Linux, including checking file encoding settings, installing and setting the system language environment, and adjusting the terminal display configuration. By setting these configurations correctly, you can avoid the problem of Chinese garbled characters being displayed in Linux systems.

Note: The above code examples are based on Ubuntu system, other Linux distributions may be slightly different.
