`secrets.compare_digest()` benötigt `bytes` oder einen `str`, welcher nur ASCII-Zeichen (solche der englischen Sprache) enthalten darf, das bedeutet, dass es nicht mit Zeichen wie `á`, wie in `Sebastián`, funktionieren würde.

`secrets.compare_digest()` necesita tomar `bytes` o un `str` que solo contenga caracteres ASCII (los carácteres en inglés), esto significa que no funcionaría con caracteres como `á`, como en `Sebastián`.

Para manejar eso, primero convertimos el `username` y `password` a `bytes` codificándolos con UTF-8.

 * escaped in a general way.
 *
 * <p>A good example of usage of this class is for Java source code escaping where the replacement
 * array contains information about special ASCII characters such as {@code \\t} and {@code \\n}
 * while {@link #escapeUnsafe} is overridden to handle general escaping of the form {@code \\uxxxx}.
