I tested with Word 2007, and normal PUA characters from my font were
displayed with vertical orientation in a vertical text box, but Plane
15 PUA characters were rotated.

I also tested with Word 2016, and both normal PUA characters and Plane
15 PUA characters were displayed with vertical orientation in a
vertical text box, as you want, although there were vertical spacing
issues with the Plane 15 PUA characters which suggest that the
vertical metrics tables (vhea and vmtx) in the font are not being
applied for Plane 15 characters (or it could be a problem with my
font).
