To identify if PDF extraction has junk values


Since UiPath doesnt have the intelligence to identify if PDF has hand written content, Is there a way we could check using some regex pattern or something else? Since its a scanned document and OCR interprets the hand written characters as some junk values, is there a work around? Appreciate your help in this

For OCR-extracted text, you can check on the confidence level in the DOM variable in its Metadata
