How to get Vim in cygwin/Windows to underline the CursorLine properly?

Question

Here is a portion of my .vimrc :

set background=dark
set cul
hi CursorLine term=underline cterm=underline gui=underline

On Linux, vim displays fine and the cursor line is underlined with a thin white line. Using the same .vimrc file on Windows (under cygwin), the cursor line has a dark red background instead of being underlined. No amount of playing with hi CursorLine seems to do the trick. Is there a way to underline the current line on Cygwin/Windows or is that a limitation of the Windows command window?

Answer 1

This is a failing in the Windows console; it has no way to render underlined text, but uses colors instead.

With an XTerm or other terminal software the underlining should work fine as long as you have

:set cursorline
