Determines whether a URL string is valid.
 
At present the only check is whether the string appears to be prefixed with a URI scheme.  It is not determined whether
the URI scheme is valid or whether the URL is otherwise well formed.


|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.
local function check_url( url_str )
return url_str:sub(1,2) == "//" or url_str:match( "^[^/]*:" ) ~= nil; -- Protocol-relative or URL scheme
end


|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:
--[[--------------------------< S A F E _ F O R _ I T A L I C S >----------------------------------------------
|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
Protects a string that will be wrapped in wiki italic markup '' ... ''
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.
Note: We cannot use <i> for italics, as the expected behavior for italics specified by ''...'' in the title is that
they will be inverted (i.e. unitalicized) in the resulting references.  In addition, <i> and '' tend to interact
poorly under Mediawiki's HTML tidy.

Joins a sequence of strings together while checking for duplicate separation characters.
 
This function sets default title types (equivalent to the citation including |type=<default value>) for those citations that have defaults.
Also handles the special case where it is desirable to omit the title type from the rendered citation (|type=none).


TODO: safejoin() has a flaw where it won't remove the duplicate character from a |title= / |url= combination.
This is because by the time we get here, |title=http://somesite.com and |title=Document Title. have been combined:
[http://somesite.com and ''Document Title.'']
so that now, the last character is not sepc but is ] (unless sepc == ']' which breaks the external link)
