When I set fillchars=stl:x statusline=a%=b, I see the following statusline:
axxxxxb
When I set fillchars=stl:· statusline=a%=b (· = middle dot, U+00B7), the status line becomes:
a-----b
The same happens with Unicode box drawing characters (they become -).
I would have expected:
a·····b
What am I missing or doing wrong?
If I don't set statusline to anything, then the default statusline draws the Unicode character correctly, something like:
~/.vimrc·····1,1·····Top
Looks like Vim does not currently support multi-byte fill characters in custom status lines (version 8.1.2203):
/* Can't handle a multi-byte fill character yet. */
else if (mb_char2len(fillchar) > 1)
fillchar = '-';
To work around the issue, I created a function that draws the line instead:
function StatusLine()
let left = 'a'
let right = 'b'
let spacer_width = winwidth(0) - len(left) - len(right)
let spacer = repeat('·', spacer_width)
return left . spacer . right
endfunction
set statusline=%{StatusLine()}
This is currently not supported.
Quote from :h 'fcs':
for "stl" and "stlnc" only single-byte values are supported.
