Yes, org-string-width eventually calls string-width, so that behaves
"correctly" as far as it goes, but unfortunately that's not where the
value in the text properties comes from...

《蛙》
123456

Doesn't that line up for you? Those bracket characters come with their
own "whitespace", maybe this is clearer:

正能量
123456

One Chinese character should definitely take up two screen columns.

I'd love to file a bug report but I honestly don't know where this comes
from. If it's not org-add-props or relatives, what emacs function is
responsible?

Thanks for the swift responses!
