How often do single dots stick to the top of kanji?


In Chinese, characters with a single dot on top stay separated from the rest
of the character. (Eg. [Chinese
宝](http://www.visualmandarin.com/tools/chinese-stroke-order/22668))

In kanji, this is frequently not the case - virtually all 宀 characters I see
have dots stuck to the 冖 part (宝, 字, etc.). On the other hand, there are a few
kanji I've seen that don't involve 宀 and so the dots are separated: eg. 主.

Do **all 宀 kanji** have the dots stuck to the top? Perhaps there are kanji
with both 丶 and 冖 but the two don't form a connected 宀. Do **all other single
dot kanji** have the dots separated (like 主)?

_Edit._ Just found that the dots are stuck in kanji with 广 radicals. Would
still like to know when the dots are stuck and when they are not stuck. Is
there a rule?




Japanese elementary school children are generally taught to write kanji like
this ([教科書体](https://japanese.stackexchange.com/q/18782/5010)):

I don't know how these are different from how Chinese kids are taught to write
these characters.

However, this largely depends on the font, and adults actually handwrite these
dots in many ways according to their preference. Practically, there is no
strict rule here, and whether or not the dot touches the bar below is not very
important. That said, I feel the dot in `宀` written by young people are
usually connected to the `冖` part.

Although this article caused some controversy, it extensively discusses
typical differences between 明朝体 (≒common "serif" font) versus handwritten
kanji, and the wide range of variations of handwritten kanji. Specifically,
this article says "dots" in 安, 言, etc. are written by hand in many ways, and
the subtle variations don't matter. (well, at least in the everyday life of
adults)
