How has Unicode/Charset issues changed in recent Java versions?

In recent Java versions, Unicode and Charset issues have become increasingly important as globalization necessitates the proper handling of character encoding across different languages and platforms. Java has evolved its handling of Unicode and charsets significantly, providing better support and integration with modern applications. Key changes include enhanced support for Unicode through updated libraries, the introduction of new character encodings, and improvements in the default character set across platforms.

One notable update in Java is the consistent use of UTF-8 as the default charset in many environments, which aligns with the standard encoding used on the web. This change reduces the risk of character encoding issues that often arise in earlier Java versions. Additionally, the java.nio.charset.StandardCharsets class was introduced, providing a standard way to represent common charsets.

These enhancements have resulted in fewer encoding problems, making it easier for developers to work with international text without encountering unexpected behavior or data corruption.

    // Example of reading a file with UTF-8 encoding in Java
    import java.nio.file.Files;
    import java.nio.file.Paths;
    import java.nio.charset.StandardCharsets;
    import java.io.IOException;
    
    public class ReadFile {
        public static void main(String[] args) {
            try {
                String content = new String(Files.readAllBytes(Paths.get("example.txt")), StandardCharsets.UTF_8);
                System.out.println(content);
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
