      abstract     = {We present our first set of results for charm physics,
                      using the mixed-action setup introduced in a companion paper
                      [1]. Maximally twisted Wilson valence fermions are used on a
                      sea of non-perturbatively O(a)-improved Wilson fermions,
                      made up by CLS $N_\mathrm {\scriptstyle f}=2+1$ ensembles.
                      Our charm-sector observables are free from $O(am_c)$
                      discretisation effects, without need of tuning any
                      improvement coefficient, and show continuum-limit scaling
                      properties consistent with leading cutoff effects of
                      $O(a^2)$. We consider a subset of CLS ensembles –
                      including four values of the lattice spacing and pion masses
                      down to 200 MeV – allowing to take the continuum limit and
                      extrapolate to the physical pion mass. A number of
                      techniques are incorporated in the analysis in order to
                      estimate the systematic uncertainties of our results for the
                      charm quark mass and the $D_{(s)}$-meson decay constants.
                      This first study of observables in the charm sector, where
                      the emphasis has been on the control of the methodology,
                      demonstrates the potential of our setup to achieve
                      high-precision results.},
