Strip wiki italic and bold markup from argument so that it doesn't contaminate COinS metadata. This function strips common patterns of apostrophe markup. We presume that editors who have taken the time to markup a title have, as a result, provided valid markup. When they don't, some single apostrophes are left behind.

There are three options for math markup rendering that depend on the editor's math preference settings. These settings are at Special:Preferences#mw-prefsection-rendering and are PNG images TeX source MathML with SVG or PNG fallback

All three are heavy with html and css which doesn't belong in the metadata.

Without this function, the metadata saved in the raw wikitext contained the rendering determined by the settings of the last editor to save the page.

This function gets the rendered form of an equation according to the editor's preference before the page is saved. It then searches the rendering for the text equivalent of the rendered equation and replaces the rendering with that so that the page is saved without extraneous html/css markup and with a reasonably readable text form of the equation.

When a replacement is made, this function returns true and the value with replacement; otherwise false and the intital value. To replace multipe equations it is necesary to call this function from within a loop.

Cleanup parameter values for the metadata by removing or replacing invisible characters and certain html entities.

2015-12-10: there is a bug in mw.text.unstripNoWiki (). It replaces math stripmarkers with the appropriate content when it shouldn't. See https://phabricator.wikimedia.org/T121085 and Wikipedia_talk:Lua#stripmarkers_and_mw.text.unstripNoWiki.28.29
