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.

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