When switching to the English-Dvorak layout using C-\ or C-x RET C-\ ,
and then turning on caps lock, the following letters do not capitalize:
w, v, z, and s. Other letters capitalize just fine. Moreover, some
secondary punctuation marks appear without pressing the shift key. For
instance, when pressing the semi-colon/colon ';' key, the colon ';'
character appears. The following punctuation keys are affected:
comma/less-than, period/greater-than, and semi-colon/colon. All other
keys in the main typing area of the keyboard do not seem to be
affected. The above error occurs even when running 'emacs -Q' and in all
editable buffers.

Here is a brief overview of the environment. The hardware keyboard used
is a typical US ANSI (QWERTY) keyboard. The operating system is Trisquel
5.0 GNU/Linux with GNOME 2.32.1, with USA as the default keyboard
layout. The GNU Emacs version is 23.2 installed from the
repository. Locale settings are:

LANG=en_PH.UTF-8
LANGUAGE=en
LC_CTYPE="en_PH.UTF-8"
LC_NUMERIC="en_PH.UTF-8"
LC_TIME="en_PH.UTF-8"
LC_COLLATE="en_PH.UTF-8"

LC_ADDRESS="en_PH.UTF-8"
LC_TELEPHONE="en_PH.UTF-8"
LC_MEASUREMENT="en_PH.UTF-8"
LC_IDENTIFICATION="en_PH.UTF-8"
LC_ALL=

Pasted below are details generated using the report-emacs-bug command. I will try to fix the problem myself, but in the meantime, I'm forwarding this bug report.

So to summarize, with a standard QWERTY English keyboard:

emacs -Q
C-x RET C-\ english-dvorak RET

Now pressing the key labelled "," produces "w" as it should, and
pressing "shift ," (ie, "<") correctly produces "W". This is because
latin-post.el has the correct mapping:

 ("W" ?<)

But when caps-lock is active, pressing "," still generates "," (not "<")
so Emacs still translates it to "w" (not "W").

I don't know if quail has any way to solve this...

One thing you can do is redefine your Caps Lock key to be a Shift Lock.
Eg using the following in Xmodmap works for me:

  keycode 66 = Shift_Lock
  add lock = Shift_Lock

I don't know if there is, or should be, an equivalent Emacs-only solution.

I think that at the Lisp level, the necessary information is not
available, so we'd have to change the C code to provide extra info for
Quail to try and use it.
It's not clear to me how best to do it, so I think it'll have to stay as
one of those "patches welcome" items.

This was nine years ago, but I can still reproduce this issue in Emacs
28, so I guess nobody's implemented this yet.
