An attempt has been made to search for the most common syntaxes first,       thus maximizing performance. Syntaxes that begin with the same character       are searched for at the same time.       Supported wiki syntaxes from most common to least common:           internal link [http:// named external link]             {| table |}           http:// bare external link           =Heading= * unordered list # ordered list : indent ; small heading  horizontal line italic bold three tildes username four tildes signature five tildes timestamp &entity; The tag-matching regex follows the XML standard closely so that users won't feel like they have to escape sequences that MediaWiki will never consider to be tags. Only entities for characters which need to be escaped or cannot be      unambiguously represented in a monospace font are highlighted, such as       Greek letters that strongly resemble Latin letters. Use of other entities is discouraged as a matter of style. For the same reasons, numeric entities should be in hexadecimal (giving character codes in decimal only      adds confusion). Newlines are sucked up into ending tokens (including comments, bare      external links, lists, horizontal lines, signatures, entities, etc.) to       avoid creating spans with nothing but newlines in them.
