Here's what I'd start with:
chidot=: #@[ ({. i. }.) ,
If that was too slow, I'd probably build an explicit work-alike, with
intermediate variables for shapes.
(>;:'SF SY PK ...') chidot (>;:'SF SY')

I often get tripped up with different trailing shapes when using i. with
char arrays. I must not be the only one[1]
Does this look like a suitable utility to deal with it or is there a more
common way?

idotfill =. (( ( (_,]) {. Y1@[) i. ((_,]) {. Y2@[) ) {:@$@Y2 >. {:@$@Y1) f.
