This will only work when the file actually *IS* encoded in ISO-8859-1.

The XML declaration isn't a processing instruction.

This is currently outside the scope of the DOM spec (DOM level 2 doesn't treat saving at all). As far as I know, MSXML should support setting a processing instruction with target "xml" and value "version='1.0' encoding='ISO-8859-1'" and later will use the encoding value when saving.
