|script-title= holds title parameters that are not written in Latin based scripts: Chinese, Japanese, Arabic, Hebrew, etc. These scripts should not be italicized and may be written right-to-left. The value supplied by |script-title= is concatenated onto Title after Title has been wrapped in italic markup.

Regardless of language, all values provided by |script-title= are wrapped in ... tags to isolate rtl languages from the English left to right.

|script-title= provides a unique feature. The value in |script-title= may be prefixed with a two-character ISO639-1 language code and a colon: |script-title=ja:*** *** (where * represents a Japanese character) Spaces between the two-character code and the colon and the colon and the first script character are allowed: |script-title=ja : *** *** |script-title=ja: *** *** |script-title=ja :*** *** Spaces preceding the prefix are allowed: |script-title = ja:*** ***

The prefix is checked for validity. If it is a valid ISO639-1 language code, the lang attribute (lang="ja") is added to the tag so that browsers can know the language the tag contains. This may help the browser render the script more correctly. If the prefix is invalid, the lang attribute is not added. At this time there is no error message for this condition.

At this writing, only |script-title= is supported. It is anticipated that additional parameters will be created to use this function.

Returns the language name and associated ISO639-1 code. Because case of the source may be incorrect or different from the case that Wikimedia uses, the name comparisons are done in lower case and when a match is found, the Wikimedia version (assumed to be correct) is returned along with the code. When there is no match, we return the original language name string.

mw.language.fetchLanguageNames() will return a list of languages that aren't part of ISO639-1. Names that aren't ISO639-1 but that are included in the list will be found if that name is provided in the |language= parameter. For example, if |language=Samaritan Aramaic, that name will be found with the associated code 'sam', not an ISO639-1 code. When names are found and the associated code is not two characters, this function returns only the Wikimedia language name.

Get language name from ISO639-1 code value provided. If a code is valid use the returned name; if not, then use the value that was provided with the language parameter.

There is an exception. There are three ISO639-1 codes for Norewegian language variants. There are two official variants: Norwegian Bokmål (code 'nb') and Norwegian Nynorsk (code 'nn'). The third, code 'no', is defined by ISO639-1 as 'Norwegian' though in Norway this is pretty much meaningless. However, it appears that on enwiki, editors are for the most part unaware of the nb and nn variants (compare page counts for these variants at Category:Articles with non-English-language external links.

Because Norwegian Bokmål is the most common language variant, Media wiki has been modified to return Norwegian Bokmål for ISO639-1 code 'no'. Here we undo that and return 'Norwegian' when editors use |language=no. We presume that editors don't know about the variants or can't descriminate between them.

See Help talk:Citation Style_1#An ISO 639-1 language name test

When |language= contains a valid ISO639-1 code, the page is assigned to the category for that code: Category:Norwegian-language sources (no) if the page is a mainspace page and the ISO639-1 code is not 'en'. Similarly, if the parameter is |language=Norwegian, it will be categorized in the same way.
