RE: Invalid high surrogate character (0xDEB6).

Thanks for your reply Dave,

I think it would be better to identify those nodes that may contains the
pontential problemtic data. Sure, you can perform an additional encoding on
the data so as to ensure it is proper unicode text range.

As you mentioned that all the data is of ASCII char, how were those ASCII
chars generated and embeded into the XML document?

My problem is I don't control the text that goes in many of the nodes &
attributes. Should I be encoding the text somehow? I assumed using the
XmlDocument methods that it would handle any necessary encoding.

Also, all of the text added in this case is ASCII.

Hi Dave,

As for the "Invalid high surrogate character" error you encountered, it
is
due to some Unicode specific validation in .NET XML API. Within the .Net
framework, there are lot of string validations for Unicode, not only for
XML. So, this is the correct behaviour.The problem is that the data in
the
XML you generated may contains some certain value that is valid in
string
or XML, but not valid for UNICODE(utf-16 which has rules for surrogate).

From some former issue, I found that you may encounter this error when
you've encrypted some of the data in the xml which may cause the
generated
value be invalid according to unicode surrogate pair rules. Is there
any
particular data included in your XML document? You can try simplify the
XML
document so as to locate the certain data fragment.

BTW, here is a blog article I've found which also mentioned this:

I am building an XML document using the standard calls to create
elements
and
attributes. Occasionally I get the following when calling
xmlDoc.OuterXml.
What's going on and how do I avoid this?

System.ArgumentException occurred

character must have a value from range (0xD800 - 0xDBFF)."
