OCRs don't hallucinate outputs = if it says "212.99mm" on architecture diagram it doesn't suddenly turn into "2413m" on the other end, because LLM thought this feels better. I remember reading on HN where that was happening in a such case (but sadly my google foo fails me to find a link)

The case you might be thinking of is the JBIG2 implementation bug [1, 2] in Xerox photocopiers where the pattern-matching would incorrectly treat certain characters as interchangeable, leading to numbers getting rewritten in spreadsheets.
