If I do
C-u C-s [:ascii:]

I get matches for :, a, s, c and i.

That does not jibe with

(info "(elisp) Char Classes")

which is explicitly mentioned in

(info "(elisp) Regexp Special")

How come we have this feature _documented_ in full detail, but not
implemented?

You need to search for [[:ascii:]] instead.

AIUI the delimiters for such symbols are [: and :].  To specify a
character class containing exactly the ASCII repertoire, use [[:ascii:]].

Try [[:ascii:]] instead.

Ah, ok.

Sorry for the noise.

It seems that special syntax deserves an example in the manual...
