I made some optical character recognition on a scanned PDF File. The original document contains special characters like öäü and so on. The problem is that sometimes the characters get recognized wrong (ex. ö=u), Preview will then let me highlight the character image ö but when copying the character it will output u.

Can Preview show me what the actual recognized characters are without the Image?

No, Preview cannot do this. What you have is a PDF document where the original image is overlaid on the recognized text. You will need a PDF editor to delete the image.

You could also select and copy the entire document, then paste it into a text editor and review the recognition there.
