Meaning of font variation in the case of the character 賭


Some Kanji characters are written slightly differently in the Mincho/Gothic
typefaces or handwriting. Ones that come to mind are 令、心, and these have been
discussed before [1]. This font-dependent variation is consistent when the
character occurs as a sub-element of another character (e.g. as in 冷).

Today, I encountered the character 賭 (as in 賭け, 賭博) that looks like it's
consists of the sub-elements 貝 and 者. Interestingly, the Mincho font on my
machine puts one extra stroke on the top right of the 日 on the right hand
side.

I was puzzled because the character 者 by itself doesn't show this variation.
Thoughts?

冷?](https://japanese.stackexchange.com/questions/3191/why-are-there-two-

In fact, the 者 character has the dot in the [Kangxi
dictionary](http://www.kangxizidian.com/kangxi/1210.gif). This variant is
coded in Unicode as 者 and is etymologically the older one.

It is worth pointing out that 賭 was only added to the Jōyō kanji list in 2010.
Computer fonts usually use traditional (= Kangxi) shapes for characters not on
the list; cf [Asahi characters](http://en.wikipedia.org/wiki/Asahi_characters)
and [extended shinjitai](http://en.wikipedia.org/wiki/Extended_shinjitai).
Curiously, if you look at the [official
list](http://www.bunka.go.jp/kokugo_nihongo/joho/kijun/naikaku/pdf/joyokanjihyo_20101130.pdf),
they explicitly say (p. 3) that this variation is permitted for 賭:
