Emacs : GNU Emacs 28.2 (build 1, x86_64-pc-linux-gnu, GTK+ Version

Package: Org mode version 9.6
This commit [[https://git.savannah.gnu.org/cgit/emacs/org-mode.git/commit/?id=3502ce2dbb29b70cdbb978d144322d48cb00f26d][ox-odt:
Fix newlines replaced by spaces in Han script]]
brings in a strange bug.
Exporting ODT produces an unexpected space inserted into each line.
Eg, the simplest code (a consecutive line conposed of two contiguous lines)
#+begin_src org
那时，天下人的口音、言语都是一样。
那时，天下人的口音、言语都是一样。
#+end_src
will produce following text:
#+begin_example
那时，天下人的口音、言语都是一样。那 时，天下人的口音、言语都是一样。
#+end_example
Notice the second sentence, the space in `那 时'.
The space seems to be inserted randomly. With more detailed example
(provided as attachment), I find that only one space were inserted into
each consecutive line, at nearly middle of the whole line.
If I manually change the code of this commit back to previous
implementation, these unexpected spaces disappear.

Thanks for reporting!
Fixed, on bugfix.
https://git.savannah.gnu.org/cgit/emacs/org-mode.git/commit/?id=cd967ce00
That was rather silly. I forgot that Chinese characters occupy two columns.
P.S. As Chinese user, do you have other gotchas Org might need to
address?

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.

There is `org-time-stamp-custom-formats' variable, which is used when
exporting timestamps. Do you need a separate variable for export only
(that does not affect `org-display-custom-times')?

This is not a bug, rather deficiency of Org's table alignment code.
The current code only takes into account the number of symbols, but not
their actual width in pixels.
The current approach reasonably good for actual plain text alignment,
but we can indeed do better wrt how tables are displayed in Emacs.
There is an existing package that implements this feature:
https://github.com/casouri/valign
Nobody proposed an equivalent patch for Org so far.
