Help:Bad title/ja

Some page titles are defined as bad for various reasons. You can't create pages with these titles.

For details of what constitutes a bad title, see regex section or.

For reference here is an example of a horrible, but valid title:


 * Some¬`!"£$^&*_+-=~?/.,;:'@

Things you can't use in titles:


 * The following standard CGI chars are not good:
 * https://www.mediawiki.org/wiki/Some%s — Very bad!


 * The following standard wiki syntax seems to work:
 * https://www.mediawiki.org/wiki/Some%sSome[s — gets trimmed
 * https://www.mediawiki.org/wiki/Some%sSome]s — gets trimmed
 * https://www.mediawiki.org/wiki/Some%sSome{s — bad
 * https://www.mediawiki.org/wiki/Some%sSome}s — bad


 * and some just don't work:
 * https://www.mediawiki.org/wiki/Some%sSome#s — gets trimmed


 * and some HTML like constructs are very bad, and can't be show here because they break page formatting:
 * https://www.mediawiki.org/wiki/Some%sSome s — bad
