Whoops.  Sorry, typo.  166CC should have been 1D6CC.

I was actually looking at the Unicode 5.1 character data base,
but the copy I keep on my own machine is the 4.0.0 version,
and those mathematical symbols were there back in 4.0.0.

I'd rather not have to write \x as λ x with a space required after the  
λ.
I suspect that "λ is the lambda-symbol iff it is not preceded by any
identifier character and is not followed by a Greek letter" might work.
