Well, 8-bit terminals are no longer that common (at least when developing Emacs)
so it's no big deal either way, and as it's easier to do it without highlighting
let's try it that way. A proposed patch is attached; it worked for me.

That can easily happen with other characters, but in practice nowadays I think
everybody has glyphs for curved quotes. This is in part due to Microsoft
Windows putting curved quotes in their most-popular 8-bit character set starting
with MS-Windows 1.0 in 1985. This put a lot of pressure on everybody else to
support these glyphs one way or another, and it has been thirty years now....
