  Condensate of a charged boson fluid at non-integer dimensions between 2 and 3
is studied. Interaction between particles is assumed to be Coulombic, and
Bogoliubov approximation is applied for a weak coupling regime. The condensate
and the superfluid fraction at finite temperatures and at non-integer
dimensions are calculated. The theoretical results are compared with the
superfluid densities of superconducting films, which show a universal splitting
behavior. The qualitative similarity between the charged boson fluid and the
superconducting films gives a strong clue for the origin of the universality.
