Title: Make block cursor cover character underneath it

The block cursor does not completely cover characters that are wider than a non-breaking space (the width is set at one single " "), such as CJK characters.

This change updates the `CursorView` with the character under the cursor whenever it moves (i.e., "cursor:moved").

* CJK Character

I'm not quite sure how to write the specs for this, though...
