In a multilanguage environment, a locale supports one script and one set of cultural attributes. An application inherits all the language and cultural attributes of the current locale. Document text is written in one script and text manipulated according to the locale language rules. A separate application launch in another locale is required to use different language and cultural attributes.
For example, to write a document in Chinese, a user first sets the Chinese locale before launching the application. To write a Russian document, the Russian locale must be separately set and the application launched again. Chinese and Russian text cannot be mixed in the same document
