[vile] Tips for improving UTF-8 display?

[Marc Simpson]

Morning all,

I've recently been editing files containing less common unicode characters, e.g.

---8<---
«🐧␤»
«🔔␤»
«⚾︎␤»
---8<---

Unfortunately, these don't display too well in Vile (with either
ncurses or ncursesw): see https://imgur.com/a/qLGfc for a comparison
of Vile (9.8t, latest from Tom's vile-snapshots repo), Vim 8 and
BBEdit.

Any suggestions for improving character rendering here?

Thanks,
Marc
