Announcement Universal Language Selector
The Universal Language Selector (ULS) provides a flexible way to configure and deliver language settings like interface language, fonts, and input methods (keyboard mappings). From June 11, 2013 on, ULS is being made available to all Wikimedia wikis in 5 phases.
It is now active on over 150 Wikimedia wikis, including English language Wikipedia and Wikimedia Commons.
On July 9, 2013, the ULS deployment will be completed by making it available to all other Wikimedia wikis (phase 5).
Where to find the Universal Language Selector
The ULS can be visible in two ways: In the sidebar as an icon that looks like a gear for wikis with language versions, like Wikipedia, or in the personal toolbar at the top of wiki pages for wikis without language versions, like Wikimedia Commons and Meta-Wiki. Clicking the icon opens the Language settings panel that can be used to set the display and input settings. Based on the geographic location of users, the initial set of language preferences is presented. Users can set the input methods and fonts to that they want to use. Logged-in users can also change the language for the MediaWiki menu items.
Please have a look at the Universal Language Selector feature description or the Frequently Asked Questions for more detailed information.
