Hi Mike

This is the original bug that started cursor movement changes:
https://sourceforge.net/tracker/index.php?func=detail&aid=3040720&group_id=588&atid=100588
(there is a lot of info and links there)

First idea of fixing the bug was to have arrows move by a codepoint. 
Final decision was to go a step farther and move by combined characters. 
Definitely old behaviour was wrong, but seems like codepoint operations 
are also desired. They will never cause data corruption, what was the 
case in character operations (see the bug).

As I understand the main problem, it is inserting codepoints like accent 
sign. One has no such character on the keyboard. So the most 
straightforward solution is copying and pasting it, like Mike used to 
do. Other possibilities are:

1. having a macro that inserts accent sign
2. using character map
3. copying only complete characters; that is if you want a+acute find it 
and copy, don't use e+acute to produce a+acute

None of the 3 solutions seems to be as flexible as copying and pasting 
combining characters, although they are possible workarounds. It seems 
like a good idea to allow for codepoint movements and editions though.
