Exceptions due to control characters

[Mosa Yeung]

Hi guys,

I've encountered a situation where I have control characters (in this case, 
&#xF) being written to xml and read back out for output. XMLFormatter was able 
to write it to the xml file without escaping it, but XMLSanner emits an 
'XMLErrs::InvalidCharacterRef' on attempting to parse it. I actually don't care 
to have the control character pass through correctly, I just want it not to 
cause the whole parse to fail.

What's the "correct" way to deal with these control characters?
