Java Error - error: illegal character: '\u203a'

package digits;

import java.util.*;

public class NameLength {

    public static void main(String[] args) {
        
    
        Scanner scan = new Scanner(System.in);
        
        System.out.println("Enter your name");
        
        String name = scan.nextLine();
        System.out.println(name.charAt(0));
        if(name.charAt(0) › 48 && name.charAt(0) < 57) {
            System.out.println("Invalid name");
            System.exit(0);
        }
        else
        {
            System.out.println("My name is: " +name);
            System.out.println("The string length of '" +name + "' is : " +name.length());
        
        }
    }
}

Okay so I want to check if string starts from a number and if it is not starting from a number I want to print the length of it. I dont know why this is giving me error. What wrong in this piece of code?

error: illegal character: '\u203a' if(name.charAt(0) › 48 && name.charAt(0) < 57) {
