|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 <bdi>...</bdi> 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 <bdi> 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.

with the calculated value.  Incorrect length (8 digits), characters other than 0-9 and X, or checkdigit / calculated value mismatch will all cause a check issn
 
error message.  The issn is always displayed with a hyphen, even if the issn was given as a single group of 8 digits.

uses characters that contain diacritical marks, those characters are to converted to the corresponding Latin character.

Validates language names provided in |language= parameter if not an ISO639-1 code.  Handles the special case that is Norwegian where
 
ISO639-1 code 'no' is mapped to language name 'Norwegian Bokmål' by Extention:CLDR.
 
 
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.

When |language= contains a valid ISO639-1 code, the page is assigned to the category for that code: Category:Norwegian-language sources (no) if

Sometime after this module is done with rendering a citation, some C0 control characters are replaced with the
