Yes! We have added localization support inside the Complete UI using the language preference setting inside the user's web browser.
English, French and Japanese are currently supported and we are looking to add more languages in the future (German and Hindi will be added in the June 2019 release).
If you would like to help us by contributing a language translation, please let us know and we would be happy to provide you with the translation list. We appreciate your help!
PDF documents that specify a Right-to-Left reading order (such as Arabic and Hebrew and vertical writing systems such as Chinese, Japanese, Korean) are also supported in all IDRViewer modes. The layout direction in magazine layouts is updated and the navigation buttons are swapped to match the document direction.
