This is the {{case preserving encode}}

meta-template.

This template is used inside the templates {{sec link}}

, {{sec link auto}}

, and {{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.
