yep. works for me here :-)

daily diff with create-as-modify import took 1h10m, which is awesome.

the only problem now is trying to import the 28-29 diff because of the 
UTF8 truncation issue. is the easiest way to deal with this just to wait 
for next week's planet? i imagine the alternative is fiddling around 
with the diffs by hand to make the string valid?

cheers,
