Accented letters in "export Recordset As XML"

Good Morning, i'm using "export Recordset As XML" i noticed that in the text strings inserted in the databse are used particular characters (in this case the accented letters used in the italian language,i.e. à,è,ò,ù) there isn't any result in XML format.If I use "e" instead of "è" it works perfectly.Is the any solution to this problem?Because I'm referring to the italian language,it's hard to avoid the accented letters wich are very common in this idiom.
