-20412 SERIALIZATION OF AN XML VALUE RESULTED IN CHARACTERS THAT COULD NOT BE REPRESENTED IN THE TARGET ENCODING

Explanation
 Serialization of XML data may require conversion
to an encoding different from the source UTF-8 encoding. If characters
exist in the source encoding that cannot be represented in the target
encoding, code page conversion produces substitution characters which
are not allowed in the result of XML serialization.

System action
 The statement cannot be processed.

Programmer response
 Choose a target encoding that can represent
all characters in the XML value. Unicode encodings are recommended
as they can represent all characters.
