The PT application is designed to be a globalized solution that can support international users; however, localization for Germany, Japan, and the United States does not address some issues that can appear when extending localization to additional countries. For example, the PT application is not localized for any locales that use bidirectional text and does not address those development issues. The following table compares the localization issues addressed by the PT application with those required for a localization effort that includes all languages.
