Replacing non-ascii characters with their ascii equivalent or removing them

Let say you have this:

var name = "ÄBÖ";

and you want to convert it to

name = "ABO";

The following snippet will do it in Java. IT also will remove the characters that don't have any alternative in ASCII characters such as ß.

String subjectString = "öäü";
subjectString = Normalizer.normalize(subjectString, Normalizer.Form.NFD);
String resultString = subjectString.replaceAll("[^\\x00-\\x7F]", "");

  }
 
  static getGenderMale() {
    return "male";
  }
}

class MaleHuman extends Human {
  constructor(name) {
    super(name, Human.getGenderMale());
  }
}

class FemaleHuman extends Human {
  constructor(name) {
    super(name, Human.getGenderFemale());
  }
}

var jack = new Human("Jack", Human.getGenderMale());
console.log(jack);

var peter = new MaleHuman("Peter");
console.log(peter);

var sarah = new FemaleHuman("Sarah");

Numeric Password Dictionary File

Today I wondered how big will be a dictionary file containing all numeric passwords of 8-digit numbers (with padding zeros).
