Finds the font in _s_e_t_s most closely matching _p_a_t_t_e_r_n and returns the result of FFccFFoonnttRReennddeerrPPrreeppaarree for that font and the provided pattern. This function should be called only after FFccCCoonnffiiggSSuubbssttiittuuttee and FFccDDeeffaauullttSSuubbssttiittuuttee have been called for _p_a_t_t_e_r_n; otherwise the results will not be correct. Returns NULL if an error occurs during this process.
