## Про данные формы ("Form Data")

Способ, которым HTML-формы (`<form></form>`) отправляют данные на сервер, обычно использует "специальную" кодировку для этих данных, отличную от JSON.

**FastAPI** позаботится о том, чтобы считать эти данные из нужного места, а не из JSON.

        // and overlong 2-byte form.
        if (byte1 < (byte) 0xC2 || bytes[index++] > (byte) 0xBF) {
          return false;
        }
      } else if (byte1 < (byte) 0xF0) {
        // Three-byte form.
