ArgumentException when writing strings with control characters

[yv989c]

The XML 1.0 spec which is used by the underline XmlWriter does not allow some control characters and may be others.

I don't think that the current runtime exception provides a good UX.

Some options:

• Translate these invalid XML characters to a common placeholder.
• Remove these invalid XML characters from the string.

I believe this is a corner case though but is still a limitation because these characters can be stored using the varchar and nvarchar data types in SQL Server.
