If the font lacks a glyph for ZWS, then the next font from the font-family list
will be used as fallback, and eventually the system fallback font will be used.
Is it really the case that not even the system fallback font has a glyph for
ZWS, or is there some other bug? If it’s the former, then maybe the fix should
be targeted at the system fallback font case only somehow.
