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.

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.
