[Octave-bug-tracker] [bug #52145] Copy and paste results in strange output

[Dan Sebald]

Follow-up Comment #5, bug #52145 (project octave):

 Average Training CE 2.712
Finished Training.
Final Training CE 2.712

Average Training
For reference, I've imported into a hex editor and I'll replace the characters
with hex format bytes:


E1 8A BD Average Training CE 2.712 0D 0A
Finished Training. 0D 0A

The prepended characters are


E1 8A BD
C4 80
CC 80
CC 80

D4 80

D0 80

EA 87 AF E0 A0 80
E0 AC 80


The 80 hex shows up a lot and looks to be a qualifier to place some sort of
apostrophe on the following character.  80 is the first character in the
extended ASCII character set, i.e., the highest ASCII character is 7F.

Could you experiment a bit with how exactly the text is selected.  For
example, I'm wondering if selecting with the mouse from the left edge is
capturing some characteristic about the window.  For example, rather than
selecting "Average Training...", try selecting "erage Training..." and pasting
a few times to see if the extra characters show up when selecting something in
the middle of a line.  (No need to attach results, rather simple give an
assessment if anything is different in that case.)

You could also try detaching the Command Line window from the app desktop and
then repeat your original example.  To detach, click the little windows icon
next to the 'x' of the editor tab Command Window.

I would think the fact that sometimes there are no extra character pre-pended
is an indication of copy-time rather than paste-time issues.
