That's a different issue. You said "\x905" was wrong visually, so I
asked how is that different, visually, from "\2205".

Same thing happens when you copy/paste from an Emacs window which uses
a display table: the pasted string will be different from the original
one. I believe I already pointed that out in this discussion.

In those cases, the octal notation has the same visual problems.

I still don't understand how this is different from the octal
notation, but if it is, you can always stay with the default octal
display. That's what I do.
