Hello,
I have GNU Emacs 24.1.1 (i686-pc-linux-gnu) of 2012-06-14.
I experience a strange behaviour with outline-mode (and also in
org-mode) :
(emacs is started with emacs -Q)
Say I have a buffer with the two lines:
* A
Some text
and I hit C-c C-d (hide-subtree) and M-<. Now I have:
* A...
^
where '...' indicates hidden text and '^' indicates the
position of the cursor (on the title line).
Then hitting C-f a few times will advance the cursor successively :
* A...
^
* A...
^
* A...
^ <- I did not expect this.
* A...
^
The behaviour that I expected was :
* A...
^
* A...
^
* A...
^ <- different
* A...
^
And in fact, adding 'text' when in the situation
* A...
^
gives the following situation:
* Atext...
^
I am a little bit worried that I do not find references to this
behaviour on the net ; am I the only one experiencing this ?
Thanks for your help.

The three dots here are not characters, they are a single graphical
entity (a "glyph"). Moving the point after the "A" character leaves
the cursor one "visual character length" before the end of the glyph,
hence what you observe.

That's because, even though the point visually appears right before the
end of the glyph, it *is* right before the whole glyph. I agree this
looks wrong.
Note that in org-mode, when `org-catch-invisible-edits' is non-nil, it
will help you catch edits in such invisible areas.

No, you aren't the only one.
This is a bug. Please use "M-x report-emacs-bug RET" to report it.
Thanks.
