Combining characters

For invisible characters (such as control characters) or for whitespace, the character and its surrounding bdi element should be omitted

I wonder if we should do the same for combining characters, otherwise it will look weird. Another approach is to use a U+25CC DOTTED CIRCLE before the combining character.

My recommendation for combining marks is:

1. if there's a webfont which supports display with a dotted circle (most Noto fonts do that now), then leave it alone
2. otherwise, use an image – i have a supply of those that can be copied, where appropriate

I don't recommend just dropping the character.

Agreed. I'll raise a PR to add this to specdev. Thank you!
