Manual:Page title/de

A page title is the title of a page. It is stored in the table. When one is specifying a certain page by typing it into the search box, or putting it in an article as a wikilink, the input consists of a (or no namespace, if it's mainspace) followed by a colon (optional if it's mainspace) and then the database key. For example, specifies the Manual: namespace and the page table database key.

The page title is case-sensitive except the first character. You can set to false to make the first character case-sensitive. However it's currently impossible to make the page title completely case-insensitive (T2453).

Invalid page titles
The following are not valid as page titles:

Note that a title can be displayed with an initial lower-case letter, using or the lowercase template. This does not fix every occurrence, like the history, edit, or log pages (T55566) - or the browser address bar (T63851), but only affects the page title on the rendered HTML page and tab/window title bars. Note that the plus sign + is allowed in page titles, although in the default setup for MediaWiki it is not. This is configured by setting the value of in. Be aware that non-ASCII characters may take up to four bytes in UTF-8 encoding, so the total number of characters you can fit into a title may be less than 255. For example, the name is not possible if Project: is set as a namespace alias. For example, an article about the album "Q: Are We Not Men? A: We Are Devo!" cannot have that exact name, as the "q:" prefix leads to Wikiquote. ( The restriction includes the prefixes "w:" and "en:" that refer to English Wikipedia itself. Diese Selbstreferenzbeschränkung gilt nicht für alle Projekte. Beispielsweise unterstützt Wikiquote Titel, die mit "Q:" beginnen.) Eine Liste all dieser Interwiki-Präfixe finden Sie auf Special:Interwiki. Zum Beispiel kann ein Titel nicht mit folgendem beginnen: "HELP:", "HeLp:", "Help :", "Help:_", and the like. However it cannot contain % followed by two hexadecimal digits (which would cause it to be converted to a single character, by percent-encoding).
 * Base names beginning with a lower-case letter (in any alphabet), depending on the setting of.
 * Titles containing the characters  (which have special meanings in Wiki syntax), the non-printable ASCII characters 0–31, the "delete" character 127, or HTML character codes such as &amp;amp;.
 * Special characters like  are translated into their equivalent %-hex notation
 * Base names beginning with a colon (:).
 * Base names equal to "." or "..", or beginning "./" or "../", or containing "/./" or "/../", or ending "/." or "/..".
 * Base names whose length exceeds 255 bytes.
 * Titles containing "Talk:" in front of a namespace.
 * Titles with an invalid UTF-8 sequence.
 * Titles beginning with a namespace alias (WP:, WT:, Project:, Image:, on Wikipedia).
 * Titles beginning with a prefix that refers to another project, including other language Wikipedias, e.g. "fr:" (see Interwiki links and ).
 * Titles beginning with any non-standard capitalization of a namespace prefix, alias or interwiki/interlanguage prefix, or any of these with a space (underscore) before or after the colon.
 * Titel, die nur aus einem Namensraum-Präfix bestehen, während nach dem Doppelpunkt nichts steht.
 * Titles beginning or ending with a space (underscore), or containing two or more consecutive spaces (underscores).
 * Titles containing 3 or more consecutive tildes.
 * Ein Titel kann normalerweise das Zeichen % enthalten.
 * Note also that it is not possible for editors to create page titles beginning with the virtual namespace prefixes Media: and Special:.

Special cases
Alternative per-namespace configurations are possible. See $wgCapitalLinks and $wgCapitalLinkOverrides. One simple way to fix this is wrapping the pagename in  from the  extension.
 * By default, titles starting with a lowercase letter are automatically converted to leading uppercase.
 * The magic words PAGENAME and FULLPAGENAME return encoded strings in which some types of characters, such as apostrophes, are converted to numeric character sequences. This means that while apostrophes are perfectly valid in page names, you may encounter issues when reusing those strings for some purpose.
