Describe your issue

I typed Chinese in a .org file. If I closed any fold (a heading, or the property), the Chinese font would be like \346\350. Only org-mode's fold led to this, while other code folds (python, cpp) would not. I checked the code-system is UTF-8.

Steps to reproduce

I re-produced with the default doomemacs config.

Does this happen when you toggle folds with org-cycle (on TAB)?

Does this happen when you toggle folds with org-cycle (on TAB)?

Yes. Happened when toggling headings or props.

[hlissner]

Yes. Happened when toggling headings or props.

In that case, this seems like an upstream issue and should be reported to org.

[PannenetsF]

I would test it via emacs -Q and create an issue to a certain upstream repo if possible.

A quick way to test it in vanilla Emacs is:

1. M-x doom/sandbox
2. Insert this into the sandbox buffer:

   (require 'org)
   

3. Type C-c C-c to launch the sandbox (vanilla Emacs),
4. M-x find-file and open the example file containing Chinese characters,
5. Use TAB (or M-x org-cycle) to try and reproduce the issue.

I am currently unable to reproduce it with vanilla Emacs or vanilla Doom.

[PannenetsF]

sandbox is really helpful while I never knew that before. I could still reproduce the CJK issue.

Hi @hlissner , did you test it on MacOS or other systems? Currently, I only have access to MacOS
