Hello,

For Redact 5.3.1, there is a strange edge case that results in the OCR not recognizing words when surrounded by equal dashes. For example, " --- Hidden Text --- " is not recognized by the OCR but " --- Hidden text -- " is recognized.

I was wondering if anyone has ran into this problem and/or has a solution to this. This seems like a weird edge case but someone might have run into this before.

Hello,

I am not sure what you do you meant with "Redact 5.3.1", but please provide test case to reproduce problem.

For me tesseract works:

I apologize, I meant "Tesseract 5.3.1", and some test cases are linked here. None of these show up in the HOCR.
