 This was one of the errors picked up when I ran your xml through:

Instead of unidecode(uniencode(myXML,"UTF8"),"ANSII") for the whole

So you do this for any node data? In other words before adding any data to a
node you should run it over a handler like this?

on xml_SafeEncode @nodeContents
    put unidecode(uniencode(nodeContents,"UTF8"),"ANSII") into nodeContents

    -- Remove byte order mark from UTF8 text
    put numToChar(239) & numToChar(187) & numToChar(191) into testBomHeader
    if char 1 to 3 of utf8Text = testBomHeader then
        delete char 1 to 3 of tVar
    end if
end xml_SafeEncode
