Issue

There are a few combining characters in Unicode which are basically different kinds of underlining. For example "combining low line" (U+0332) or "combining wiggly line below" (U+1AB6). It seems to me that these should be continuous or at least have an option to be continuous. Right now they overlap each other in a non-continuous way or for letters with descenders (see the letter g in the screenshot below) the line is not at the same height as the others.

I'm not sure if the current implementation is correct or not as very few fonts even support these characters. So maybe this is more of a feature request than a bug report?

Also, the anchor point for the "a" in Noto Serif is clearly too far to the right.
