The composed char is displayed as a normal ASCII `a'. Visited literally, the file looks like this: Rilke Sings N\303\270rga\314\212rd N\303\270rga\314\212rd But visited in utf-8-unix with auto-composition-mode enabled, the cursor behaves strangely. When I move the cursor to the `a' on the first line with `C-f' or `C-b', the cursor disappears. It reappears when I move the cursor away from the `a' with any cursor motion command. Moving the cursor to the same `a' with `M-x goto-char 17' causes both the cursor and the character to disappear (it is displayed as an empty space). `C-l' makes the `a' reappear, but the cursor remains invisible. The cursor behaves normally with the `a' in the second line. I also tried viewing the same file with `emacs -Q -nw norgard' in an xterm. Both instances of `N=C3=B8rga=CC=8Ard' appear as `N=C3=B8rg= rd ', with a diacritical ring above the `g' and two spaces after the `d'. With the cursor over `=C3=B8', `C-f' moves to the `g', skipping over the `r'. I'm using GNU Emacs 23.0.60.3 (i686-pc-linux-gnu, GTK+ Version 2.8.20).
