From `emacs -Q`, I write `(kbd "C-x ( C-d C-x )")` in the buffer, then
evaluate it using `C-M-x`, which gives "^D" instead of the expected
"^X(^D^X)". This can be seen more clearly by calling `key-description`
with the result from `kbd`, resulting in "C-d" instead of the expected
original string "C-x ( C-d C-x )". (Thanks to thblt from #emacs for this
minimal example).
The original problem was found when trying to call emacs keystrokes on
an input file (with the goal of achieving something like vim with the
`-c` flag) like so,
`emacs -Q --insert input.txt --eval '(command-execute(kbd"C-x ( C-d M-0
C-x )"))'`
Running this removes only 1 character from the input file instead of
every character being deleted as expected.
Another instance of this bug is https://emacs.stackexchange.com/q/33395
(thanks again to thblt for finding this).
These results were as tested on GNU Emacs 26.3.

That's because kbd is just a wrapper around read-kbd-macro.

Yes, and FWIW Emacs always worked like that (I checked a far back as
Emacs 23.1).

FWIW, I just checked Emacs 20.7, and it's the same.

Ah, intended behaviour then, read-kbd-macro's help file documents this
so that resolves the issue. Thank you all for your swift replies.
So how would you solve the original problem of calling emacs
keystrokes with potential keyboard macros inside them?
`command-execute` appears to use `execute-kbd-macro` according to the
source, so trying `command-execute` on each keystroke does not work as
intended with `C-x ( ... C-x )` among the commands.

Good question. More generally, given the textual representations of any
number of Emacs keystrokes, do we have a way to get those replayed
programmatically? I thought we had (on top of `call-last-kbd-macro' or
edmacro), but I can't really find anything now?

I've now fixed this in Emacs 29. `key-parse' now returns [24 40 4 24
41] for that sequence, while `kbd' maintains the backwards-compat code.
(This has been broken for half a year and nobody noticed -- in Emacs 29,
(kbd "C-x ( C-d C-x )") returned "" instead of "^D", so it's debatable
whether it makes sense to keep the compat code, but at least we do for
now.
