My query using LIKE operator returns no results

I am trying to run a query on workbench mysql to find results using the LIKE operator but it is coming up with no results. I even changed LIKE operator with REGEXP but still get no results. Adding % doesn’t help as well.

SELECT *
FROM Employees
WHERE first_name LIKE 'Jo?n'
ORDER BY first_name;

SELECT *
FROM Employees
WHERE first_name LIKE 'Jo?n'
ORDER BY first_name;
