Manual:$wgFragmentMode/ja

Determines how section IDs should be encoded.

Details
この配列は1つまたは2つの要素を含むことができます. 各要素は以下のいずれかです：


 * ' ' - 最小限のエスケープであるモダンな HTML5 スタイルエンコーディング. 多くのブラウザのアドレスバーにおいて Unicode 文字が表示されるようにします.
 * ' ' - 古い MediaWiki スタイルエンコーディング. 例：啤酒 は .E5.95.A4.E9.85.92 になります.
 * ' ' 非推奨の モードに対応します. そのモードを止めるための移行以外では使用しないでください（以下を参照）.

The first element of this array specifies the primary mode of escaping IDs. This is what users will see when they e.g. follow an to a section of a page.

The optional second element defines a fallback mode, useful for migrations. If present, it will direct MediaWiki to add empty to every section with its id attribute set to fallback encoded title so that links using the previous encoding would still work.

Example: you want to migrate your wiki from 'legacy' to 'html5'. On the first step, set this variable to [ 'legacy', 'html5' ]. After a while, when all caches (parser, HTTP, etc.) contain only pages generated with this setting, flip the value to [ 'html5', 'legacy' ]. This will result in all internal links being generated in the new encoding while old links (both external and cached internal) will still work. After a long time, you might want to ditch backwards compatibility and set it to [ 'html5' ]. After all, pages get edited, breaking incoming links no matter which fragment mode is used.
