>>And yes, your б is unnatural a bit, although it is understandable.
It is understable because it has context, you know that it is б and nothing else. Also with the line which is under the word this letter could be д as well, without this line it looks more like o. IMHO б should look like б.

Мне показалось, или в вики на картинке написано "Цыфры"?
