The XHTML migration dies on this exception:

It looks like the whole process dies, and not just the batch. Forcing the upgrade task again fails at the same point.

[CONFSERVER-23316] XHTML migration dies on java.io.IOException: The character '^K' is an invalid XML character
Actually I've found much more control characters which I have had to remove manually from DB. Thanks for fixing that issue soon.
RE: Lukas Koranda, the latest comment in your support ticket indicates that the issue in your migration was not with the british pound symbol but with the record separator symbol ("^^" with ASCII value 30).
This is addressed in the upcoming fix.
We've discovered that this is due to Xerces complaining about control characters in the range of 0 to 32 (exclusive of 32, 9, 10, 13) being found in CDATA.
We are working on a fix that will strip these characters before we allow Xerces a chance at processing them.
It happens for me in the same manner but in my case it stops on British pound sign. This is really silly.
I upgraded from confluence 3.4.9 --> 3.5.13 --> 4.0 last night and had to roll back to 3.5.13 due to this issue. We are reluctant to edit the DB manually not knowing what the impact will be.
I didn't notice this in my test environment, but I'm going to go back and try this again there to see what happens. If you have a newer release with this fix in it, I'm happy to give that a go for you and provide all the logs.
