-----------------------------------------------------------

Some characters actually need to be filtered out as even after escaping they 
cannot be represented in XML [1].

> If invalid characters are entered through the UI, they can corrupt the 
> flow.xml.gz making it unparsable on future restarts. Once in this state, the 
> flow.xml.gz needs to be hand-edited to remove the invalid characters. The 
> following characters may cause issues:
> {code}
> #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF]
> {code}
> {code}
> [#x7F-#x84] | [#x86-#x9F]
> {code}
