Yes.

I'm not sure, either. The second way happens when we generate the
glyph matrices -- do we select font before or after that? If after,
we probably look for a font that supports all of the characters in the
composition. Perhaps Handa-san could comment on this.
But, at least in my testing, I used a font that definitely supports
both characters, and the composition still didn't happen.
