How to type these old and rare Chinese characters? I've tried to google these old Chinese characters using their closest approximations but still haven't found out any. I want to find these characters so that I can copy and paste them instead of taking photos of them every time needed. They are:  

PS: I just added 3 more Old Chinese characters because before that I didn't have enough reputation to upload more than 2 images. So, at the beginning, there were 2 images but after adding 3 more, now there are 5 images.
If you're having trouble displaying the following characters install the Hanazono font.

石 毛 doesn't seem to have much of a record as far as I can tell.


No results found for “⿱石毛”.

where ⿱ means top/bottom components in order of: 石(top) 毛(bottom)
 日 also doesn't seem to have an exact match that I can find, but this website seems to say it's this:



⿱日[T]

they say it's a combination of  日 but the character looks more like 干 than 于, not sure if it will work for your purpose.
zisea 肰

How to find characters?
1
I used zisea's 两分 to find both characters.
For the first one I searched 羽 能 (with a space in the middle)

and for the second I searched 高 毛 (with a space in the middle).

If you can figure out the two major components you can pretty much find any character you want, unicode or non-unicode.

笔顺
zdic sou suo page explains it like this:

请输入正确的笔顺编码：李→1234521
笔顺说明
笔顺名称   一（横）    丨（竖）    丿（撇）    丶（点）    乛（折）
笔顺编号   1   2   3   4   5
注:一（提）归为一（横），亅（竖钩）归为丨（竖），丶（捺）归为丶（点），各种折笔笔画归为一（折）——《现代汉语通用字笔顺规范》

 for instance is 丶一丨フ一丨フ丨フ一ノ一一フ which equates to 41251252513115
if you search for this on zdic select 字典 and then 笔顺 you'll get something like this:

google components
&quot; 日&quot; google search

If you try an exact search (quoted) for the components you are looking for you might also find what you want. That's how I found  referenced as a combination of the two, obvious, components of your character.
