Re: Re: Can't isearch 'ö'

Hello!

I deleted your patch from keyboard.c, i.e. renamed the file and took 
the copy of the original keyboard.c Emacs built yesterday when I 
applied your patch. Then I remade emacs (make clean; make bootfast) and 
launched the unpatched and the version like:

env LANG=de_DE.ISO8859-1 LC_CTYPE=de_DE.ISO8859-1 src/emacs -q -g 80x45 
&
env LANG=de_DE.ISO8859-1 LC_CTYPE=de_DE.ISO8859-1 /usr/local/bin/emacs 
-q -g 80x45+750+25 &

With C-d I opened in dired mode the directory with my test files. 
Pointing on a file with the mouse cursor opened it in the other or a 
newly created buffer. To search for é I entered: C-s ´ e.

Initially unify-8859-on-decoding-mode was off, after the first tests I 
switched that mode on via ESC-x unif TAB de TAB RET.

With your patch to keyboard.c it works, i.e. i-search é finds the 
character in my test file "ISO 8859-15.txt", without the patch it does 
not work, i.e. i-search does not find é.
unify-8859-on-decoding-mode's value is nil.

With your patch to keyboard.c it does not work, i.e. i-search é does 
not find the character in my test file "ISO 8859-15.txt", without the 
patch it works, i.e. i-search finds é.
unify-8859-on-decoding-mode's value is t.

Yes, it just moves it.

This means that I have to correct my email from yesterday night. 
Somehow. The difference is that you have to close the buffer, then 
toggle unify-8859-on-decoding-mode's value, then open the test file 
again. Only this does en effet change the value and the success 
i-search has or has not.

Testing is fine, but causes some work!
