The SilverStripe CMS content editing interface has now been translated into Chinese, Japanese, and Arabic, which combined are spoken as a first language by far more people in the world than English. Download SilverStripe 3.1.1 or try it out in the demo.
SilverStripe is translated into many other languages - from Norwegian and Russian to Czech and te reo Māori (see video). If you know a language besides English, we would love you to review and contribute translations.
SilverStripe CMS seperately supports publishing pages in other languages, and can be configured to enable unicode URLs, i.e. to make URLs that are readable to Chinese, Japanese, and Arabic website visitors.
