If a file is written using one encoding and read using another, the text may appear as unreadable symbols. Using UTF-8 consistently prevents this problem.

BufferedReader br = new BufferedReader(
    new InputStreamReader(
        new FileInputStream("data.txt"),
        "UTF-8"
    )
);

In this example, Java reads the file using UTF-8 encoding, ensuring that all characters are displayed correctly.
