Aparently humans are almost as prone to this. I don't know how many HP410B VTVMs I've seen advertised as an HP4108.

The biggest problem with OCR especially with manuals is that The OCR
engine unlike we humans is not context sensitive,? for example often"I"
,"l" and "1"? (pronounced , eye , el and one) are confused by the OCR
engine ("B" and "8: are the next candidates). This is particularly
problematic on Schematics and especially HP parts lists which were often
printed with a tiny 6pt font. OCR engines are designed with text
dialogue and news paper column in mind. Schematics are also a big
problem as a result because the OCR engine doesn't always know what to
do with R101 ( was that an "O" or a "0" ) hanging out in space and not
part of sentence. You and I reading it know that is R101 and not RLOL
because we read it in context. Hp at one point made it even worse as the
font they used was identical for lower case "L" and the number "1"

Hi David,
Absolutely correct and I'd certainly persist with OCR if I was getting
good results.
