create a file with the following 2 lines of unicode char.

⇒⇒⇒⇒
⇒⇒⇒⇒

(these are just repeated character of unicode #x21d2)

place your cursor in one of the arrow. Move your cursor left and right. 
Then, press arrow up or down to move cursor to the next line.

Expected behavior is that they move to the same column as the previous line.

What actually happens is that the cursor got moved one column less. That is, 
more to the left.

Might try to move around the arrow a bit in order to reproduce this problem. 
I think you might have to move cursor left rigt on the same line first.
