Invalid XML character error

See original GitHub issue

Hi team!

We are observing the following error while performing a request to AdGroupAdService via the SDK:

An invalid XML character (Unicode: 0xb) was found in the element content of the document.

Looks like the service is returning the symbol 0xb that causes XML deserializer to fail. Here’s the SDK-related part of the stack trace. Is there a way to handle this on our side without making changes to the data?

Caused by: org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 4743; An invalid XML character (Unicode: 0xb) was found in the element content of the document.
