Minor Description
I would like to add a method that replace accented caracter by unaccented one. For example, with the input String "L'été où j'ai dû aller à l'île d'Anticosti commenca tôt", the method would return "L'ete ou j'ai du aller à l'ile d'Anticosti commenca tot".
I suggest to call that method unaccent and to add it in StringUtils.
If we cannot covert all case, the first version could only covert iso-8859-1.
If you are willing to go forward with that idea, I am willing to contribute a patch.
