My apologies for posting here, I can't get posting rights at
gmane.emacs.help. My `return-confirmation' emails get bounced at that
news-group.
The development emacs-27 version recently changed the default character
seen when entering a password from `.' to `*'. I want to get back to the
old default, but
(let (read-hide-char) "?.")
does not work, and my e-lisp knowledge is insufficient to understand the
reason. What am I doing wrong?
Thanks.
Colin.

'let' specifies a list of variable bindings, and you want the
character '.', not a string containing '?' and '.', so itʼs:
(let ((read-hide-char ?. ))
(message "%c" read-hide-char))

Unfortunately
(let ((read-hide-char ?. ))
(message "%c" read-hide-char))
also doesn't work. It gives the error
Wrong type argument: characterp, "?."
as soon as I enter a password. The same error occurs if I use
`emacs -q'. Could this be a bug?
Best wishes,
Colin.

Hmm. Could you show a full transcript of what youʼre doing? Donʼt
forget that the let-binding is only valid within the let, not for the
entire session. If you want it to valid all the time you'll need to do
(setq read-hide-char ?.)

Ok, that explains things I think. At the beginning, I wanted to set `.'
as the read-hide-char in my emacs-init file, but the doc string for
read-hide-char says it should never be set globally. I took that to mean
never to set via a `setq'. This seemed to be confirmed in comments of
the lisp/subr.el file, where using a let-bind is suggested. Hence my
efforts at writing a `let' to my emacs-init, which maybe were a little
naive.
The (setq read-hide-char ?.) does indeed work, and seems to do so
without creating errors elsewhere. So I'll leave it in my ~/.emacs for
now. However, I am now curious as to what the sentence, `This variable
should never be set globally.' means in the doc-string for
`read-hide-char'. Perhaps the doc-string could be amplified slightly?
Thank you very much for your help.
Best wishes,
Colin.

I suspect there are situations where having read-hide-char set causes
things to be hidden that shouldn't be, hence it should only be set
temporarily. Maybe someone on the list here knows.
