for what it's worth, without the symbola font on my machine (though i've now added it), i seem to see the left-arrow 2b60 rendered using: ---- ftcrhb:-GNU-Unifont-normal-normal-normal-Sans-Serif-16-*-*-*-c-80-iso10646-1 (#x2B61) ---- (if i'm interpreting the output of [C-u C-x =] correctly.)
cheers, Greg
