Reminds me a bit on (windows) Notepad. It used to throw a message
at the user:

    There are no changes to be saved - Ok | Cancel

...wich left zillions of users headshaking. Stupid thing. Is it so hard 
to save anyways?

Actually it serves a purpose except from not prohibiting what is doing 
no harm.
Saving an unmodified buffer should cause another application with the same
buffer open to update.

As far as I can see one can get scintilla to ignore these chars on 
keyboard input.

If one wants to play around with control chars use CharTables.
