       FriBidiStrIndex *position_from_this_list

              List of embedding levels.


       This  function  removes  the  bidi and boundary-neutral marks out of an
       string and the accompanying  lists.   It  implements  rule  X9  of  the
       Unicode        Bidirectional        Algorithm        available       at,  with  the  exception  that  it
       removes U+200E LEFT-TO-RIGHT MARK and U+200F RIGHT-TO-LEFT MARK too.

       If any of the input lists are NULL, the list is skipped.  If str is the
       visual  string,  then  positions_to_this   is    positions_L_to_V   and
       position_from_this_list  is  positions_V_to_L;   if  str is the logical
       string, the other way. Moreover, the position  maps  should  be  filled
       with valid entries.

       A  position  map  pointing to a removed character is filled with ‐1. By
       the way, you should not use embedding_levels if str is visual string.

       For best results this function should be run on a whole paragraph,  not
       lines;  but  feel  free to do otherwise if you know what you are doing.
       Deprecated.  Use fribidi_remove_special_chars instead.


       New length of the string, or ‐1 if an error occured (memory  allocation
       failure most probably).
