  Log Message:
  -----------
  Misleading unicode identifier detection pass

Detect when an identifier contains some Right-To-Left characters.
This pass relates to https://trojansource.codes/

Example of misleading source:

    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);
    }

This is a recommit of 299aa4dfa1d8c120648b1404b481d858b76c8173 with missing
option registration fixed.
