Why does Java execute code written in comments using Unicode characters?

Hi everyone! I'm new to Java and encountered a strange behavior that I can't explain. I was trying to write a simple "Hello, World!" program, but accidentally discovered that code inside comments can be executed if you use Unicode escape sequences. Here's an example that confused me: ```java public class Main { public static void main(String[] args) { // \u000d System.out.println("This executes!"); System.out.println("Hello, World!"); } } ``` When I ran this code, two lines appeared in the console: "This executes!" and "Hello, World!". But the first line is a comment! How is this possible? I thought comments are ignored by the compiler. I've read that this is related to how Java handles Unicode, but I don't understand the details.
