If you are sure that your strings are ASCII, why doing 
Conv(TheString, "UTF-8", "ASCII")?

And the error message printed by the underlying iconv library is clear: your 
string is not ASCII.

According to you, The toString() methods always returns an accurate string.

According to the source code, Conv() receives a non-ascii string.

Can you check that, by splitting your code?

FOR EACH oItem IN oGroup.Items
  sType = oItem.toString()
  sType = Conv(sType, "UTF-8", "ASCII")
  oXml.Attribute(oItem.Name, sType)
NEXT

As for the crash with attributes values larger than 2000 characters, I will 
look later. But maybe you could send me a little project that shows the bug 
in that specific case? It will help a lot.
