     * Available options:

     *      type: boolean

     *      description: replace ASCII characters of the translated string with accented versions or similar characters

     *      type: float
     *      default: 1
     *      validation: it must be greater than or equal to 1
     *      description: expand the translated string by the given factor with spaces and tildes
     *      example: if 2, "foo" => "~foo ~"

     *  * brackets:
     *      type: boolean

     *      description: wrap the translated string with brackets

     *  * parse_html:
     *      type: boolean
     *      default: false
     *      description: parse the translated string as HTML - looking for HTML tags has a performance impact but allows to preserve them from alterations - it also allows to compute the visible translated string length which is useful to correctly expand ot when it contains HTML
     *      warning: unclosed tags are unsupported, they will be fixed (closed) by the parser - eg, "foo <div>bar" => "foo <div>bar</div>"
