  Users of Heegaard Floer homology may be reassured to know that it can be made
to conform exactly to the standard analytic pattern of Lagrangian Floer
homology. This follows from the following remark, which we prove using an
argument of J. Varouchas: the natural singular K\"ahler form $\sym^n(\omega)$
on the $n$th symmetric product of a K\"ahler curve $(\Sigma,\omega)$ admits a
cohomologous smoothing to a K\"ahler form which equals $\sym^n(\omega)$ away
from a chosen neighbourhood of the diagonal.
