unicode_decompose_func_t(ufuncs: unicode_funcs_t, ab: number, a: number, b: number): number
A virtual method for the #hb_unicode_funcs_t structure.
This method should decompose an input Unicode code point,
returning the two decomposed code points in #hb_codepoint_t
output parameters (if successful). The method must return an
#hb_bool_t indicating the success of the composition.
