There isn't really a "simple" way to do anything that involves drawing something step by step on screen. How exactly are you wanting to implement this, as there are several ways you could do something like this but each has it's own set of challenges to deal with.

I would recommend creating a sprite animation of the letter being drawn. This would be easy to set up in Unity with minimal code, but potentially time intensive for the creation of the sprite sheet necessary to allow for smooth animation.

Thank you for your answer, I would like to do it with only unity as a program. I was thinking doing spritesheet for every letter or even using itween for every letter. I guess I'll need many frames to make it look smoothly

Your sprites will have to be created outside of Unity, in your graphic editor of choice (Photoshop, GI$$anonymous$$P, etc.) Drawing complex shapes in Unity is a bit of a coding intensive process and something that I'm far from qualified to expand on. I do know that it would involve either using a lot of GL calls or creating a procedural mesh...beyond that I really can't say much.

The more "easy" way it is to make something what creates a procedural mesh while dragging the mouse, the tricky part it is to make the trace smaller or bigger, this to make the bold area of the letter, you need to thing like it was the line renderer from unity, check the documentation about it, cheers.
