No. In the context of computer graphis a "sprite" is a bitmap which is
*indpendent* from the screen content and can be moved around freely.

Also see: <https://en.wikipedia.org/wiki/Sprite_(computer_graphics)>

One example for the use nowadays is the mouse cursor which is often
implemented as a sprite.

But "things written on the canvas" is just like paintint something on
it. And this will become permanent - a canvas is just a bitmap on which
you can paint. You can't write a unicode symbol to a canvas and then
move it around like a sprite without destroying the background.
