Subject: 27.0.50; Character widget unable to read newline character
Date: Sun, 17 Jun 2018 08:39:15 +0200

Hello,

a recipe for emacs -Q:

(require 'whitespace)
(customize-option 'whitespace-display-mappings)

Make a change and undo it immediately so that the contents are unchanged
but customize lets you "Set for current session".  Do that and you get
the

"error custom-variable-set: This field should contain a single
character"

If I remove the entry for the newline character, it succeeds.

For debugging purposes I changed the :valid-regexp of the character
widget definition in wid-edit.el to ".*" and it seems that the newline
character is read in as empty string.

TIA,

Michael.
