This is my status bar settings:
set statusline=%{&ff}\|%{&fenc!=''?&fenc:&enc}\|%y\|c:%v\,r:%l\ of\ %L\|%f
The display effect is
unix|utf-8|PERL|c:1,r:1 of 63|256.pl
I hope to add a display item to display the number of characters contained in VISUAL mode
Write a function to calculate it yourself.
PS: g Ctrl-g can check the number of selected characters.
