Table: Languages supported by Twitter for Websites widgets and buttons

A language code may be set automatically by Twitter’s markup generators based on a logged-in Twitter user’s language setting or a language chosen in the markup generator.

<a
  class="twitter-share-button"
  href="https://twitter.com/share"
  data-lang="es">
Twittear
</a>

Twitter’s widget-js library will extract the most appropriate language from your widget’s DOM context if no language is provided in the widget markup. Pages which define a script or region subtag not supported by Twitter widgets will be mapped to the closest available language: e.g. pt-BR will use pt if Portuguese is available but a Brazilian regional localization is not.

United States English is the default if a page’s language code does not match any available translation.

Note: setting the language only affects the language of Twitter elements such as action text and timestamp display; Tweet text is always displayed in its originally authored language.
