[vile] extended characters displaying as backslash sequences on BSD

[Eur Ing Chris Green]

I seem to de dredging up all sorts of problems at the moment.

On my BSD build of vile 9.5o extended characters (e.g. accented
letters, the UK pound sign, etc.) are displaying as backslashed
sequences rather than the proper characters.

I.e for the pound sign I get \xA3 and for e with an acute accent I get
\xE9.

Vile 9.5o is working OK on other platforms and I thought that my
previous vile (9.5i or thereabouts) was OK here on BSD.  So what's
changed?

The characters display fine outside of vile.
