Thanks for your fix!

In my experience, most of weird troubles are related to the (1) language
habit or (2) mixed use of Ideographs and alphanumeric.

Eg. for (1).

The Org export option keyword `DATE' use a fixed built-in timestamp
format which is rarely used in Chinese. It's impossible to customize the
format only for exporting, without touching format in Org.

At present, I have to use a macro to format a Org timestamp to the
string, that used for `DATE' keyword.

It's best to provide a option/variable to set the timestamp format used
in exported doc.

Eg. for (2).

With `pangu-spacing' package installed, set
`pangu-spacing-real-insert-separtor' to nil. A well-chosen monospaced
font are also used to ensure one CJK character is alignment with two
Alphanumerics.

Think of following table:

#+begin_src org
| Alphanumeric | Ideograph | Symbol               | Mixed                    |
|--------------+-----------+----------------------+--------------------------|
| ABC αβγ 123  | 一二三四  | ，。、？！；：“”／‘’ | 1一B二c三α四             |
| ABC αβγ 123  | 一二三四  | ，。、？！；：“”／‘’ | A一／二“三”四            |
| ABC αβγ 123  | 一二三四  | ◉○🞛◇✿❀⚛✸     | ◉一○二🞛三◇四✿❀⚛✸ |
| ABC αβγ 123  | 一二三四  | ▶▷✶⬢⬡☀☼       | ▶▷✶⬢⬡☀☼           |
#+end_src

The right border of `Mixed' column isn't aligned, because
`pangu-spacing' insert a space between Chinese and English in an
overlay. (Actual display result as follows)

#+begin_example
| Alphanumeric | Ideograph | Symbol               | Mixed                    |
|--------------+-----------+----------------------+--------------------------|
| ABC αβγ 123  | 一二三四  | ，。、？！；：“”／‘’ | 1 一 B 二 c 三α四             |
| ABC αβγ 123  | 一二三四  | ，。、？！；：“”／‘’ | A 一／二“三”四            |
| ABC αβγ 123  | 一二三四  | ◉○🞛◇✿❀⚛✸     | ◉一○二🞛三◇四✿❀⚛✸ |
| ABC αβγ 123  | 一二三四  | ▶▷✶⬢⬡☀☼       | ▶▷✶⬢⬡☀☼           |
#+end_example

And, if I move the point vertically by Up/Down key in `Symbol' or
`Mixed' column, the point shifts left or right. This has nothing to do
with `pangu-spacing', but probably because some symbols have variable
width in a font.

Usually, I'm not sure if these problems can be called bugs, or which
extensions are responsible of them. Fortunately, these problems are
non-fatal and tolerable generally.
