Message #3 received at submit <at> debbugs.gnu.org (full text, mbox):
'C-x 8 RET' will show Unicode names when it shows completions, which
helps people find the complete name of the character they want to use.
I have a patch to do something similar for 'C-h k' and 'C-h b' (for
translated keys only), so youʼd get
'C-h k C-x 8 E' =>
€ 'EURO SIGN' (translated from C-x 8 E)
Since the purpose of this is to provide more information by default in
situations where people are searching for answers, I
donʼt think this needs a configuration variable, unlike the analogous
feaure in 'what-cursor-position'. (yes, people can hit 'C-u C-x =' in
the *Help* buffer, but first they have to know about that).
Patch to follow when I have the bug number.

Does this mean that if I type "C-h k a" I will be told that a is LATIN
SMALL LETTER A? That'd be an annoyance, I think.

Thatʼs not a translated binding, so no.
Let me attach the patches.

What is a "translated binding" or "translated key"? Without
explaining that, at least the NEWS entries are not clear enough.

How do you input 'C-h k C-x 8 E'? I can only input 'C-h k C-x 8 e'.
(Also with 'C-x 8' typing 'E' (i.e. 'S-e') inputs 'e').

Itʼs anything that goes through `key-translation-map'. How
about:
-- >8 --
*** 'C-h k' ('describe-key') shows Unicode name.
For keybindings which produce single characters via translation (such as
those using the 'C-x 8' prefix), 'C-h k' now shows the Unicode name of
the produced character in addition to the character itself, e.g.
'C-h k C-x 8 E' =>
€ 'EURO SIGN' (translated from C-x 8 E)
*** 'C-h b' ('describe-bindings') shows Unicode names.
For keybindings which produce single characters via translation, the
Unicode names will now be shown in addition to the character itself,
i.e.
A-! ¡ INVERTED EXCLAMATION MARK
A-$ ¤ CURRENCY SIGN
and so on.

Itʼs a binding I added to master on Monday. You can use
'C-h k C-x 8 * E'
instead.

Are there any other cases of "translated characters", besides "C-x 8"?
If so, please mention one or two more. If there are no other
examples, I'd remove "such as".
Otherwise, LGTM; please install.

iso-transl.el is (almost) the only thing that uses
`key-translation-map' (the other is 'double.el', but thatʼs really
niche). I can mention the other prefixes.

What about characters produced by input methods? For example:
C-u C-\ cyrillic-translit RET
C-h k z h =>
ж (translated from h ж) runs the command self-insert-command
(which, btw, uncovers a bug, since "h ж" is bogus and should be "z h"
instead).
Severity set to 'wishlist' from 'normal'
