/**
 * By default JSON output does only have escaping where it is strictly
 * necessary. This is recommended in the most cases. Nevertheless it can
 * be sometimes useful to have some more escaping. With this method it is
 * possible to use {@link StringEscapeUtils#escapeJavaScript(String)}.
 *
 * @param escapeCharacters an array which defines which characters should be
 *                         escaped and how it will be done. See
 *                         {@link CharacterEscapes}. In most cases this should
 *                         be null. Use like this:
 *                         <pre>{@code int[] esc = CharacterEscapes.standardAsciiEscapesForJSON();
 *                           // and force escaping of a few others:
 *                           esc['\''] = CharacterEscapes.ESCAPE_STANDARD;
 *                         JsonEncoder.useEscapeJavaScript(esc);
 *                         }</pre>
