Whenever I try to change a file properties to one with special letters it's automatically changes the letter to '?'.

For exaple: If I have a .mp3 sonf file and I go to the file's properties-> Details. And in the Title I want to change to name to "Mañana" ('tomorrow' in Spanish), I click OK and then go to the properties again and it says: "Ma?ana".

How can I change it so that these kind of special letters will remain and not change to the question mark?
