Drupal has some excellent translation functions but deciding which modules to use and how to configure the modules is challenging. There are many different possible configurations depending on your website needs, domain names and content. You'll find there are a lot of choices of modules for setting up a multilingual site.... then there are a lot of key configuration items to enable depending on your website.
This post focused on Drupal 6 modules and issues. We will give some example of the difficult decision making involved in translating content. There is no out-of-the-box configuration that seems to work, it all depends on the needs of your website. There are many different modules to choose from in core and contrib and a lot of their functions overlap.
The best advice is to start with the core multilingual modules and then add other modules when needed. Good Luck Bon Chance Viel Glueck 幸運 Buona fortuna 好运 Buena suerte Удача
