This template should be used on pages in the Category: namespace, and automatically generates descriptions and categorization for categories of a recognized type (see below). It is implemented by Module:category tree and its submodule Module:category tree/charactercat. It is preferable not to invoke this template directly, but to simply use {{auto cat}} (with no parameters), which will automatically invoke this template on appropriately-named category pages.

This template fills the contents for a category for terms spelled with a certain (unusual) character, such as Category:Portuguese terms spelled with Ü.


Language code and character no longer have to be entered as parameters; the module automatically determines them from the page title.

The category sort key. Only needed when the sortkey cannot be generated automatically by the language's makeSortKey function in Module:languages.
