I'm used to have display of the number of selected characters in the mode line when there is an active selection (in vim).
Is it possible to achieve this in emacs?
I managed to display the column index besides the line index, which is something... But not quite enough. I also looked at the mode line format documentation, but without success.
I also found smart mode line but I think that it doesn't offer the feature as of now.
Use library Mode-Line Position (modeline-posn.el).
It shows you the size of the selection (active region) in the mode line, using the region face. It optionally tells you also the number of selected characters or characters and lines, etc.
size-indication-mode (which might be a good thing, must get used to it). Will try this first, will probably stick to it.

The following code could be a good start for you.
(setq mode-line-format '("%e" (:eval (number-to-string (abs (- (point) (mark)))))))
This sets the mode line to display the number of selected characters. It only updates after some events, e.g. C-l.
To finish this off you'd just want to add the specified form to an existing mode-line-format variable.
(abs (- (point) (mark)))Also take a look atM-x describe-variable RET mode-line-format RET.setq-default mode-line-formathowever the abs is just not appearing. I tried adding(:evaland then it shows*invalid*
