Which OCR engine is NOT listed for use on Document Manager?

The correct choice indicates that Adobe PDF OCR is not listed for use on Document Manager. This can be understood within the context of UiPath’s available OCR engines that are integrated into their Document Manager features. UiPath Document OCR, Google Cloud Vision OCR (including its capabilities for Japanese), and Microsoft Read OCR are all recognized as supported engines due to their adaptability and compatibility with UiPath's automation framework, particularly in handling documents effectively.

Adobe PDF OCR, while a capable technology, may not be specifically integrated or supported as a standalone option within the Document Manager. This distinction is important as UiPath focuses on optimizing its architecture and workflows with engines that offer seamless integration, scalability, and support across its suite of automation tools.
