The 'useful' characters are mainly line drawing and dingbats
which are double width in the DBCS and normally single width
in UCS. (Mostly U+2400..U+2800)

Nope, there's double _spacing_ in ECMA-48 but it doesn't really fit.

I thought it'd be right to use a UCS character and I've been using U+303F
but I'm pretty sure that's wrong.
