Characters: U+3030
The current vertical orientation in the draft UTR #50: U
The vertical orientation that I recommend: T

Like U+301C (WAVE DASH), in Japanese vertical lines, its vertical-specific glyph shape should be used for U+3030 (WAVY DASH). Glyph substitution is essential, and the result shape should resemble its mirrored AND -90 degrees rotated image. So, U+3030's vertical orientation should be T.

SVO=MVO=Tr for U+3030 (WAVY DASH) will be good when most CJK fonts have the 'vert' glyph for U+3030, but unfortunately major fonts such as Hiragino and Kozuka don't have the 'vert' for U+3030.

That's no problem if the 'Tr' means Rotate if cannot Transform, but in CSS3 Writing Modes §5.1.1. Vertical Orientations the VO value 'Tr' is treated same as 'Tu' (“... If the orientation value is ‘U’, ‘T’, ‘Tu’, or ‘Tr’ then the simple value is ‘U’.”) and the WAVY DASH will be set Upright if cannot vert Transform. I think SVO=MVO=R will be better in this unfortunate situation.
