Expand description
hb_unicode_decompose_func_t: @ufuncs: A Unicode-functions structure @ab: The code point to decompose @a: (out): The first decomposed code point @b: (out): The second decomposed code point @user_data: user data pointer passed by the caller
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.
Return value: True if @ab decomposed, false otherwise
