How to create a UTF-8 encoded file in linux?

In Linux systems, there are various ways to create UTF-8 encoded files. Two common methods are listed below:

1. Use a text editor:
   Open the terminal, and then use your preferred text editor (such as nano, vi, gedit, etc.) to create a new file. Before saving the file, make sure to set the encoding of the file to UTF-8. In most editors, you can select the encoding format when saving the file or set the default encoding in the editor’s preferences.
   For example, creating a file with UTF-8 encoding using the nano editor can be done with the following command:
2. Edit the file named filename.txt using the nano text editor.
3. In the editor, you can input content and save the file by using Ctrl + O. During the saving process, you will be prompted to choose the encoding format. Select UTF-8, then press Enter to save the file and exit the editor.
4. By using the command line:
   In the terminal, you can create a UTF-8 encoded file using the echo command. The echo command is a print command that can output text to the terminal or a file.
   For example, you can create a UTF-8 encoded file containing “Hello, World!” with the following command:
5. Write “Hello, World!” to filename.txt.
6. The echo command will write the string “Hello, World!” to the filename.txt file using the above command. By default, the echo command will use the system’s default encoding, usually UTF-8.

No matter which method you choose, make sure to select or set the UTF-8 encoding when creating the file. This will ensure that the file can properly handle and display Unicode characters.
