Hello skycats,
Thanks for your post and the sample file.
While the image quality is not ideal I managed to get this result (for the first three lines of the main text):
本书的写柞缂起几年前找学习 WPFn 固为找是从 Windows Forms 开发转来做 wPF 开发的. 学习过程中
遇到帷多新概念 新特性, 其中包括 Data Binding. 路由鬟伴 命令~ 各种模板等- 我的工作风格足对于每个
新知识. 一定先把它理孵进伽 涮丑白再应用于项目中. 不然总感觉仗用起未不放心1 于是就对照已有的英
I can't quite tell if it's the correct result - but to me it looks almost as if it is.
I used "Medium" quality and "Preserve original content and add text layer on top".
Regards,
Stefan

thank you for your reply.
to see your results, I conducted some tests.
finally, I found that this is a bug
I printed a pdf file using other tools. see
- test.pdf
- (78.24 KiB) Downloaded 258 times
(above is the text, below is a screenshot)
when I use OCR Page, it works fine.
Code: Select all
我是测试文本0 我是测试文本O 我是测试文本〇
I am test text. I am test text. I am test text.
when I use OCR Image, it does not work.
Code: Select all
332%iflfliitfidio fi%ifilflifiilfio fiEifilflifiY$o
I am test text. I am test text. I am test text.
these strange characters, looks like a character encoding error

By any chance, are you using english while trying to OCR? If you are you can download alternate OCR languages here:
https://www.pdf-xchange.com/pdf-xchange-viewer-ocr
I believe this is the most likely reason behind this situation as my test with English as the selected language net similar results to your tests.

Hi skycats,
Thanks for the report.
I now managed to reproduce the issue and have created a ticket in our internal system:
#4218: Editor 323.2: OCR image does not work the same as Document -> OCR Pages...
To allow our developers to investigate and get this fixed.
In the mean time please use the Document -> OCR pages as a workaround!
Regards,
Stefan
