Small problem there with M-x describe-char:

cl--assertion-failed: Assertion failed: (not (multibyte-string-p str))

I can also see many errors:

Invalid face reference: mail-double-quoted-text-face [4 times]
Invalid face reference: mail-multiply-quoted-text-face [2 times]
Invalid face reference: mail-double-quoted-text-face [6 times]
Invalid face reference: mail-multiply-quoted-text-face [2 times]
Invalid face reference: mail-double-quoted-text-face [6 times]

Debugger entered--Lisp error: (cl-assertion-failed ((not (multibyte-string-p 
str)) nil))
  cl--assertion-failed((not (multibyte-string-p str)))
  encoded-string-description(#("�" 0 1 (charset unicode)) nil)
  describe-char(439)
  funcall-interactively(describe-char 439)
  call-interactively(describe-char record nil)
  command-execute(describe-char record)
  execute-extended-command(nil "describe-char" nil)
  funcall-interactively(execute-extended-command nil "describe-char" nil)
  call-interactively(execute-extended-command nil nil)
  command-execute(execute-extended-command)

Picture is attached showing chars.
