Help:Bad title

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 the regex in Title.php

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:
  • http://www.mediawiki.org/wiki/Some%s # Very bad!

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

• and some just don't work:
  • http://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:

** http://www.mediawiki.org/wiki/Some%sSome<s - bad
** http://www.mediawiki.org/wiki/Some%sSome>s - bad
