There are discontinuities, and if I use wide characters (like CJK spaces, e.g. '　'), portions of the line are misaligned.

At the moment boxes and backgrounds already span the full line height, so I'm assuming strike-throughs would as well. That's again not on the glyph level, it's drawing code specific to each terminal type.
