The way CJK unification works, you don't need to show that there is a
semantic difference between the two forms, just that the form is used
in a reputable source.  Can you send me off-list a scan of the
character from the Vietnamese dictionary you mention?

I think you can achieve the appropriate styling for web pages using CSS:

Even with OpenType it is not easy to contextually create a gap between
two combining underlines as the characters are not adjacent (I don't
think it is impossible, but the only way I can think of doing it is
rather unpleasant; perhaps other font experts on this list know an
easy way of doing it).

U+1AB6 is supported in the next release of BabelStone Han (due for
release very soon, probably within the next week or two).

The combining underline and wavy line characters will work OK with a
vertically oriented CJK font (they will display on the left).
Unfortunately BabelStone does not currently work very well in vertical
