If one of my characters is KO’d, does it keep its damage counters?

A KO’d character has damage counters on it equal to its health. Note that this is true even if it took
more damage while on the battlefield. For example, if a character with 7 health takes 10 damage, it ends
up in the KO area with 7 damage counters.
