Subject: 23.0.60; Dead keys do not work in dired and similar modes in Cocoa port
Date: Sat, 29 Nov 2008 16:25:34 +0100

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug <at> gnu.org  
mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Dired mode binds ~ to dired-flag-backup-files. When one attempts  
entering
~ via the dead-key combination Alt-n (assuming the Alt key is not  
used as
a modifier key and Command is interpreted as Meta key), Emacs first  
reports
an error message "Buffer is read-only: #<buffer ~>" followed by an error
message "Wrong type argument: overlayp, nil" upon the next event.

In an attempt to fix this issue with some other Emacs version, I have  
added
the lines
  (define-key function-key-map [dead-tilde] "~")
  (put 'dead-tilde 'ascii-character ?~)
to .emacs, but these do not help (nor does removing them from .emacs).

Note that with a German keyboard layout, Alt-n is the only way to  
enter a
tilde character. The ASCII tilde is not bound to any key. (Actually, one
could enter ASCII tilde via key combinations Ctrl-Alt-n and Command- 
Alt-n,
respectively, but obviously this does not work for Emacs.)
