Invalid XML character

[jtyme]

Trying to see what is best practice for handling invalid xml character (Unicode 0x3) was found in the element content.

Currently we are using the following regex
var newMessage = message.replace(/[\x00-\x08]|[\x0B-\x0C]|[\x0E-\x1F]/g, '');
And this works.

But we are using it in the Custom Attachment Javascript section. Is there a better place or process to resolve this? We can't reach out to the source of the message and need to resolve this on our end.

The preprocesor script might be the typical place peope do this.
