Finds identifiers that contain Unicode characters with right-to-left direction, which can be confusing as they may change the understanding of a whole statement line, as described in Trojan Source.

An example of such misleading code follows:

#include <stdio.h>

short int א = (short int)0;
short int ג = (short int)12345;

int main() {
  int א = ג; // a local variable, set to zero?
  printf("ג is %d\n", ג);
  printf("א is %d\n", א);
