How Do I Ensure UTF-8 Encoding When Writing Files in Java?

Specify UTF-8 Encoding for FileWriter in Java

Encountering issues with creating UTF-8 encoded files in Java? Here's how you can enforce UTF-8 encoding:

In the given code, using FileWriter alone results in 1252 codepage files. To achieve UTF-8 encoding, switch to FileOutputStream instead.

try (OutputStreamWriter writer =
             new OutputStreamWriter(new FileOutputStream(path), StandardCharsets.UTF_8))
{
    // Write UTF-8 encoded text here
}

This approach utilizes OutputStreamWriter to wrap the FileOutputStream. The OutputStreamWriter constructor allows specifying an encoding, ensuring UTF-8 encoding for your file. Note that you should enclose the code in a try-with-resources statement for proper resource management.

By following this approach, you can create UTF-8 encoded files in Java, enabling the reliable handling of Unicode characters and internationalization.
