> 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.
> Characters outside the following ranges may cause issues:
> {code}
> #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF]
