If you are running Java on English Windows platforms, it is probably Cp1252. If you are running Java on English Solaris platforms, it is most likely 8859_1
In Java, the platform’s default character encoding can be obtained using the Charset class. The default character encoding is determined by the system property "file.encoding". You can retrieve it programmatically using the following code:
import java.nio.charset.Charset;
public class DefaultCharsetExample {
public static void main(String[] args) {
String defaultCharset = Charset.defaultCharset().name();
System.out.println(“Default Character Encoding: “ + defaultCharset);
}
}
The Charset.defaultCharset() method returns the default charset for this instance of the Java virtual machine. The name() method of Charset returns the canonical name of the charset, which is the name specified when the charset was created.
Note that relying on the default character encoding may lead to portability issues, as different systems may have different default encodings. It’s often recommended to explicitly specify the encoding when working with character data to avoid unexpected behavior across different environments.
