Rule 5: VERTICAL LINE SUPERSMUSHING (code value 4096)

This one rule is different from all others, in that it "supersmushes" vertical lines consisting of several vertical bars ("|"). This creates the illusion that FIGcharacters have slid vertically against each other. Supersmushing continues until any sub-characters other than "|" would have to be smushed. Supersmushing can produce impressive results, but it is seldom possible, since other sub-characters would usually have to be considered for smushing as soon as any such stacked vertical lines are encountered.
