I think the idea is you assume uniform continuity of the set (as
expressed by a parametrized curve).  That should let you approximate
the fractal dimension.

As for countability, remember that the reals are a separable metric
space, so the value of a continuous function any dense subset of the
reals (e.g. on the rationals, which are countable) completely
determines the function, iirc.
