Many different technologies have been important in bridging the gaps; in the internationalization arena, Unicode has provided a lingua franca for communicating textual data.

However, there remain differences in the locale data used by different systems.The best practice for internationalization is to store and communicate language-neutral data, and format that data for the client.Please submit corrigenda and other comments with the CLDR bug reporting form [Bugs].Related information that is useful in understanding this document is found in the References.For the latest version of the Unicode Standard see [Unicode].For a list of current Unicode Technical Reports see [Reports].
