  A continuum approach to quark-antiquark bound-states is used to determine the
electromagnetic form factors of pion-like mesons with masses $m_{0^-}/{\rm
GeV}=0.14$, $0.47$, $0.69$, $0.83$ on a spacelike domain that extends to $Q^2
\lesssim 10\,$GeV$^2$. The results enable direct comparisons with contemporary
lattice-QCD calculations of heavy-pion form factors at large values of momentum
transfer and aid in understanding them. They also reveal, inter alia, that the
form factor of the physical pion provides the best opportunity for verification
of the factorised hard-scattering formula relevant to this class of exclusive
processes and that this capacity diminishes steadily as the meson mass
increases.
