Java Conversion table convert É to E

Is there a disign pattern that will help me convert some unicode characters to its readable counterpart?

For example:

Original converted
¿          ?              
À          A              
Á          A              
À          A              
à         A              
Ä          A              
Å          A              
Æ         A              
Ç          C              
Ø         O              
Ñ         N              
×           .              
Π           I              
Ï          I                
Р        D              
Ñ          N              

Or how would you do it?
