It seems hard to estimate the value of that, without knowing why we ran out
of characters. A slow collection of a huge number of Chinese ideographs and
new Native American scripts, maybe. Access to a library with a trillion
works over billions of years from millions of species, probably not. Given
that we're in no risk of running out of characters right now, speculating
on this seems pointless.
