On the hand, to delete characters until the first undisplayable character.

A prefix argument determines how many, so ..
C-u 2 C-k kills the next two, C-u -1 C-k text from point back to the
start of the line.
C-u C-k kills the next 4 lines.

Don't know how to do that. Possibly you could use zap-to-char.
Why on earth do you want to do that anyway?

What characters do you consider undisplayable?

It's hard to count how many spaces there are, even harder with tabs.
What's easy is that do that in one line is enough for me.

Because if the previous deleting can be done, I think it is a good
companion. :-)

1. M-\: deletes white space to the right *and* the left.
2. M-- M-\: deletes white space only to the left. (There's a bug right now
when calling delete-horizontal-space with M-\ but I'll report it.)
3. C-M-s SPC RET C-w: kills white space to the right.

But why do you want to count spaces and tabs?

Right, I think I'm still not seeing what you're trying to do. (By the
way, most Emacs people consider "undisplayable" characters to be ones
in international characters sets that can't be displayed with their
current font.)
To delete stuff that is not whitespace can also be done using regexp.
M-x replace-regexp RET \w RET RET will remove all words leaving only
punctuation and space. M-x replace-regexp \S SPC RET RET will remove
all words and punctuation leaving only space. If you use
query-replace-regexp for the commands above then Emacs will ask you
about each occurance, meaning you can do it only once, then escape by
pressing C-g.

Depending on what you need the above for, `just-one-space' (for me
M-SPC is bound to this command) might be useful to you.
