Do you have an OCR now that doesnt recognize them? If so... which characters and which OCR software are you using?

I think those symbols would be more accurately referred to as Greek letters. I'd expect the ability to recognize characters would depend on language selections.
I was trying to dereference Null Pointers before it was cool.

Of posible interest:

Unicode has a very rich set of symbols taht are not standard in ASCII.
Examples
μ β ∜  ₓ ₔ  ζ η θ

I like this one:  ∿ SINE WAVE

That could be a tough nut for OCR unless the OCR program was given a clue taht unicode was used.
