Constructor Details

#initialize(options = {}) ⇒ Transliterator

Initialize the transliterator with options

Parameters:

  • options (Hash) (defaults to: {}) —

    Configuration options

Options Hash (options):

  • :mode (String) —

    The mode of operation (“ivs-or-svs”, “base”). Defaults to “base”.

    • “ivs-or-svs”: Add IVS/SVS selectors to kanji characters

    • “base”: Remove IVS/SVS selectors to get base characters

  • :drop_selectors_altogether (Boolean) —

    Whether to drop all selectors when mode is “base”. Defaults to false.

  • :charset (String) —

    The charset to use for base mappings (“unijis_90” or “unijis_2004”). Defaults to “unijis_2004”.

  • :prefer_svs (Boolean) —

    When mode is “ivs-or-svs”, prefer SVS over IVS if both exist. Defaults to false.
