In the PDF output by OCR, the Chinese text is all n
When using OCR to recognize Chinese PDFs, it is able to recognize the text in the PDF (at least Chinese text can be seen from the output text file), but the text copied from the output PDF is all n, and if the image is cleared when exporting, it looks blank and nothing.
log:
**** Error: Tf refers to an unknown resource name: F2 Assuming it's a font name.
Output may be incorrect.
I'm running in Docker. And I installed Chinese fonts via apt install fonts-noto-cjk-extra but it still doesn't work.
I also encountered this problem. The output text file is normal Chinese text, but the Chinese text copied in the PDF is all n
I also encountered this problem. The output text file is normal Chinese text, but the Chinese text copied in the PDF is all n. However, selecting "Sandwich" in the rendering type can recognize the Chinese characters in the output, but it may not be accurate enough.

The problem description is that the OCR recognition result displays Chinese characters normally, but in the output PDF, the Chinese characters are all displayed as "n".
The Chinese language packs has been installed, otherwise the recognition result would not be displayed normally.

yes

The Chinese language packs has been installed, otherwise the recognition result would not be displayed normally.
Yes, if the language pack is not installed, only English will be displayed under "Select languages that are to be detected within the PDF (Ones listed are the ones currently detected):".
I also encountered this problem. The output text file is normal Chinese text, but the Chinese text copied in the PDF is all n. However, selecting "Sandwich" in the rendering type can recognize the Chinese characters in the output, but it may not be accurate enough.
I don't really understand the difference between these two rendering modes, but the accuracy of the recognized text should be the same, right? They are both results recognized by 'tesseract-ocr'.
And it's work for me! Thanks a lot!

We've solved the case! HOCR (Latin/Roman alphabet only) only supports Latin or Roman characters and does not support Chinese. This post can be deleted. The conclusion was derived from ChatGPT.
