  - INTL POLYFILLING and IMPLEMENTATION (Internationalisation API) -
  NOTE: In Node.js [Intl](https://github.com/nodejs/node/wiki/Intl) support is not enabled by default.
  Also Intl ICU files should be prepared and added in different ways according to the OS platform.
  Beacuse of that, Intl module is used. It provides a run-time and cross-platform solution.
