if match(line, '\V' . escape(a:char, '\') . '\v\s*$') == -1
is what I'd go for. The other approaches won't work with characters
like * and ^ for instance, and the above one will. It saves you from
having to choose individual characters to escape by switching the
regex into "very nomagic" mode for a while, where non-backslashed
characters are interpreted literally so only a backslash needs to be
escaped.
