Yes, sure.
Interesting slip-up (don't jump on me, I'm just kidding!). Please 
don't take umbrage of this unfortunate typo.
Or more likely this mistyping can be attributed to the [sp|h]ell checker.

The short answer is no.

The long explanation needs distinguishing platforms.

On Windows, the file chooser called by Tk is the platform native 
chooser provided by the OS itself. This dialog cannot be tuned and 
does not have such an encoding pulldown menu. End of the story.

On Linux, the file chooser called by Tk is a dialog implemented in Tk 
language. This dialog can in principle be tuned: this amounts to 
tweaking the source code provided by the Tk package.
In practice I would not do this, because it would cause a lot of 
headaches whenever the Tk version gets updated. Implementation of the 
chooser is not part of the public interface. The public interface is 
limited to the single command tk_getOpenFile, which has no existing 
option to show an encoding pull down menu.


I'll fix the typing mistake above in the next version of the SEP.
Besides, I have also identified (and fixed) a minor issue with the MRU 
list. The fix amounts to saving the Scipad preferences file in utf-8 
encoding instead of using the platform native system encoding.

I'll publish the updated SEP soon.
I will first wait for more comments arising from the dev list.
