- From an alternative language: This is a redirect from a page name in English to a page name in an as-yet-undetermined language. These words may directly translate or they may be related words, names or phrases.
- This redirect leads to its target in accordance with the naming conventions for titles in other languages and can help writing and searches. However, per WP:NOTBROKEN do not replace these redirected links with a piped link.
- From an alternative name: This is a redirect from a title that is another name or identity such as an alter ego, a nickname, or a synonym of the target, or of a name associated with the target.
- This redirect leads to the title in accordance with the naming conventions for common names to aid searches and writing. It is not necessary to replace these redirected links with a piped link.
- If this redirect is an incorrect name for the target, then {{R from incorrect name}} should be used instead.
- To the same page name with diacritics: This is a redirect from a page name that does not have diacritical marks (accents, umlauts, etc.) to essentially the same page name with diacritical marks or a "List of..." page anchored to a promising list item name with diacritics. The correct form is given by the target of the redirect.
- This redirect aids in searches and may be applied (without piping) when the subject page concerns language translation or foreign language equivalents. Other pages that use this redirect should be updated with a direct link to the redirect target (again, without piping).
- This rcat template must not be used to tag redirects to a title with differences that are 1: ligatures (like æ and Œ – use {{R to ligature}} instead), or 2: other non-ASCII characters that do not include diacritics (like Greek letters – use {{R from ASCII-only}} instead).
- This rcat template can also be used on redirects to sections and anchors to indicate the diacritics-free version of a term/name written both ways.
