(I'm going through old bug reports that unfortunately got no response at
the time.)

This bug is still present in Emacs 28 -- I reproduced it with

XMODIFIERS=3D"" LC_ALL=3Deo ./src/emacs -Q

(after defining the "eo" locale on this laptop).

Before I go poking into this any further -- has anybody else here on the
mailing list encountered this problem before?

This doesn't seem to happen any more, though.

Dear Emacs maintainer(s),

I am running into an unusual bug of sorts.  That is:  The behaviour of th=
e
compose key is incorrect when the locale is set to "eo" (Esperanto).  The=
 exact
behaviour is as follows:

- When running `XMODIFIERS=3D"" emacs`, `<MULTI_KEY> a e` does not produc=
e =C3=A6.  It
  simply produces nothing.  `<MULTI_KEY> ' e` correctly produces =C3=A9, =
however.

- When running `XMODIFIERS=3D@im=3Dibus emacs` (my default), simply press=
ing the
  compose key results in `<MULTI_KEY> is undefined`.

Emacs is (almost) the only program where this happens. The only other pro=
gram
that reliably fails on the same sequences is xterm.  xterm results in the=
 same
behaviour for both `XMODIFIERS` values.  All other programs (Firefox,
LibreOffice, gedit, Yakuake, etc.) function correctly.

But, when I run `LC_ALL=3Den_GB.UTF-8 emacs`, the behaviour is as expecte=
d:  All
compose key sequences just work.  The same is true for running xterm with=
 the
en_GB.UTF-8 locale.

I am running Debian Buster with GNOME on Wayland.  The bug occurs with a =
vanilla
=2Eemacs.d/ folder.  I have ibus installed and running, but also without =
ibus
running, I run into the first of the two items.

Because it happens on both Emacs and xterm, I suspect that this bug may n=
ot be
exclusive to Emacs, but I am hoping that someone with a better understand=
ing
than I could point me in the right direction.

Thank you very much.

Yours sincerely,
Carmen
