#6673

What changes did you make? (Give an overview)

Fix XML escape with ASCII control characters

Is there anything you'd like reviewers to focus on?

When generating XML report with control characters (like "\b" or "\n", they
are sometimes used in JavaScript object keys and will cause messages.),
some XML parser like SAX will crash.

Escape these characters will avoid crashing.
