Two different manipulations of PDF lead to different results：
If I use Open Adobe to annotate and highlight PDF.
(1) Highlighting and annotations are normal.
(2) I can copy and paste the Chinese inside the PDF normally and without garbled code.
Highlight or annotate operations directly in Devonthink.
(1) Highlighting and annotations show garbled code.
(2) Copy the Chinese inside the PDF, and paste it out will be garbled.
Is there anything I can do to solve this problem? Thank you for your help.
