/**
 * An [RFC 3492] punycode decoder for converting ASCII to Unicode domain name labels. This is
 * intended for use in Internationalized Domain Names (IDNs).
 *
 * This class contains a Kotlin implementation of the pseudocode specified by RFC 3492. It includes

* Um parâmetro de consulta `q` opcional do tipo `str`.
* Um parâmetro de consulta `skip` do tipo `int`, com valor padrão `0`.
* Um parâmetro de consulta `limit` do tipo `int`, com valor padrão `100`.

Os dados serão convertidos, validados, documentados no esquema da OpenAPI e etc nos dois casos.

## Utilizando { #use-it }

Agora você pode declarar sua dependência utilizando essa classe.

    private final InputLocation location;

    {
        String modelId = "org.apache.maven:maven-model-builder:"
                + this.getClass().getPackage().getImplementationVersion() + ":reporting-converter";
        InputSource inputSource = new InputSource();
        inputSource.setModelId(modelId);
        location = new InputLocation(-1, -1, inputSource);
        location.setLocation(0, location);
    }

...y declara su tipo como el modelo que creaste, `Item`.

## Resultados { #results }

Con solo esa declaración de tipo en Python, **FastAPI** hará lo siguiente:

* Leer el body del request como JSON.
* Convertir los tipos correspondientes (si es necesario).
* Validar los datos.
    * Si los datos son inválidos, devolverá un error claro e indicado, señalando exactamente dónde y qué fue lo incorrecto.

This is an "advanced" feature.

## Use cases { #use-cases }

Some use cases include:

* Converting non-JSON request bodies to JSON (e.g. <a href="https://msgpack.org/index.html" class="external-link" target="_blank">`msgpack`</a>).
* Decompressing gzip-compressed request bodies.
* Automatically logging all request bodies.

the main features needed by API systems is data "<abbr title="also called marshalling, conversion">serialization</abbr>" which is taking data from the code (Python) and converting it into something that can be sent through the network. For example, converting an object containing data from a database into a JSON object. Converting `datetime` objects into strings, etc.

Another big feature needed by APIs is data validation, making sure that the data is valid, given certain parameters. For...

    /**
     * Creates an EditBody from a StopwordsItem entity for API responses.
     *
     * @param entity the StopwordsItem entity to convert
     * @param dictId the dictionary ID
     * @return the converted EditBody object
     */
    protected EditBody createEditBody(final StopwordsItem entity, final String dictId) {
        final EditBody body = new EditBody();
        body.id = entity.getId();
