small black square - NO
My mistake.
I found that, at least for the ePubs I have encountered, searching for that small black square "■' does not really help much in finding ePubs with extensive OCR errors. When I checked ePubs with a lot of occurrences (whether or not there were also "^" warnings), that black square was almost invariably being used for other display reasons and not as an OCR error indicator.
