 // Purpose: Changes hexcharacter codes in wikilinks to actual unicode characters
 //
 // Examples: [[Stra%C3%9Fe|street]] -> [[Straße|street]]
 // [[AutoEd#History_.281990.29|History]] ->
 // [[AutoEd#History (1990)|History]]
 //
 // Note: Contributed by CharlotteWeb
 //
 // Comments (CharlotteWeb):
 // To keep things simple we'll ignore all image links. because some people prefer
 // underscores in the file name and the caption can contain god-knows-what.
 // one easy way is to flag them with a character which should never be used,
 // but if it is already present we have a problem, so let's just quit.
