   * The IDE has allowed to configure only a single font family for a while. However, that doesn't handle a situation when
   * that font family is unable to display particular char - fallback font family was chosen randomly from the whole collection
   * of all registered fonts.
   * <p/>
   * Now it's possible to specify more than one font, i.e. directly indicated 'fallback fonts sequence' (see {@link FontPreferences}).
   * However, old single font-based API is still here in order to preserve backward compatibility ({@link #getEditorFontName()} and
   * {@link #getEditorFontSize()}). I.e. those methods are just re-written in order to use {@link FontPreferences} object exposed
   * by this method.
