Changes to it can cause immediate changes to the Wikipedia user interface. To avoid large-scale disruption, any changes should first be tested in this template's [[Template:Case preserving encode/sandbox|/sandbox or [[Template:Case preserving encode/testcases|/testcases subpage, or in your own Wikipedia:Subpages#How to create user subpages|user space. The tested changes can then be added in one single edit to this template. Please discuss any changes at {{#if:|[[{{{2}}}]]|the [[Template talk:Case preserving encode|talk page}} before implementing them. }}

This is the {{case preserving encode}}

meta-template.

This template is used inside the templates tl|sec link, tl|sec link auto, and tl|sec link image. (And it might be used in other templates too.)

This template is used to URL-encode wiki page names for external links to other MediaWiki wikis. Since MediaWiki's own URL-encode functions don't work when making links to other MediaWiki wikis.

This template preserves the case of the first character, and it correctly preserves the namespace name.

Technical details

For a detailed explanation of the methods used in this template see the Template talk:Sec link#About ((sec link)), ((sec link auto)) and ((sec link image))|talkpage of {{sec link}}.
