Question

Cannot perform Simplified Chinese OCR on desktop

Whenever I try to perform OCR recognition on a scanned Simplified Chinese document on Adobe Acrobat Pro desktop, an error message pops up: Acrobat could not perform Text Recognition on this page because: Unknown error (see uploaded screenshot). The scanning quality is high. English documents scanned in the same way can be easily recognized through OCR. Meanwhile, the simplified Chinese OCR works fine on Android App.

 

When performing Simplified Chinese OCR recognition on the Android app, the app prompts me to download the Simplified Chinese language pack. However, there is no such prompt on the desktop software. I'm not sure if the problem is due to the lack of the language pack. But I've searched through preferences settings and haven't found the place to download the OCR language pack.

 

- Environment: Windows 11, Adobe Acrobat Pro (Continuous Release 2025.001.20435 64-bit)

This post solved my issue: Solved: OCR not working with Japanese and Chinese but OK w... - Adobe Community - 13188072. The problem can be solved by installing optional components in "preferences". Obviously, this is a bug affceting all non-latin language OCR. Those optional components should be installed by default. You can reproduce the bug using my attachment. Hope it get fixed.

@pnzwAhde This is likely a software issue, possibly a bug or a missing language library that the application needs to perform the recognition. There was a recent update again that may solve your issue (March 19th) . Try that out first 

Version 25.001.2043x (March 19, 2025).
