{{Lang|language code|Text}}
This template is to be used for marking text as another language. See the IANA subtag registry for language codes.
This is most important for Japanese (ja), Traditional Chinese (zh-Hant), and Simplified Chinese (zh-Hans) so that a correct font is used, as some characters look different between the three but have the same Unicode code point. Marking it for other languages does have benefits for screenreaders, however.
