Template:R to diacritic

When used inside the {{Redirect category shell}} template:

When used by itself:

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.

This template should not be substituted nor used to tag soft redirects.

Usage

This redirect category (rcat) template populates both Category:Redirects from titles without diacritics and Category:Unprintworthy redirects. In 2003, efforts were begun to support the Wikimedia Foundation's goal of increasing access and availability of Wikipedia articles in printed versions. Redirect titles without diacritical marks are not suitable for a printed version. In other words they are unprintworthy.

Add this rcat to a redirect in the following manner:

#REDIRECT [[(target page name)]]

{{Rcat shell|
{{R to diacritic}}
}}

and when the redirect is in article mainspace, printworthiness should also be tagged:

#REDIRECT [[(target page name)]]

{{Rcat shell|
{{R to diacritic}}
{{R unprintworthy}}
}}

Template {{Rcat shell}} is an alias for the Redirect category shell template, which may be used to add as many appropriate rcats as needed, usually from one to seven, along with their parameters, to a redirect. For more information see the documentation on its template page. This rcat may also tag a redirect individually:

#REDIRECT [[(target page name)]]

{{R to diacritic}}

This is in accord with instructions found at Wikipedia:REDCAT.

Use this rcat to tag any redirect in any namespace with no diacritical marks (accents, umlauts, etc.) to essentially the same page name that does have diacritical marks.
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).

Explanation

File:USASCII code chart.png

ASCII chart from MIL-STD-188-100 (1972); b1 is the least significant bit.

A basic ASCII character is any one of the 128 alphanumeric and other characters that are standard keyboard symbols (see article for more information).

A diacritical mark is a symbol added to a letter that functions to change its pronunciation, meaning, or other characteristic. Accents and umlauts are examples of diacritical marks. Conversely, ligatures and standard Greek letters are not diacritical.

Since names using such characters may not be searchable to some Wikipedia users (i.e., they cannot be typed in the search bar without using the copy-paste function, advanced technical knowledge or additional aids such as keyboard mapping software), most such titles should be transliterated into the common English representation per Wikipedia:Romanization and moved to that name. For the titles that properly do and should use special characters and diacritics per Wikipedia naming conventions, their romanized equivalents should be redirected and categorized using one of the templates mentioned below.

Redirect templates

Any redirect title in any namespace that contains only ASCII characters and redirects to a title containing one or more non-ASCII characters should use the template:

{{R from ASCII-only}}

Any redirect title that contains one or more non-ASCII characters and redirects to a title containing only ASCII characters should use the template:

{{R to ASCII-only}}

An example is a redirect title containing a hyphen (-) that targets an article title that replaces the hyphen with an endash (–). The hyphen is an ASCII character while the endash is non-ASCII.

Any redirect title that contains only ASCII characters and redirects to the same title except that it contains one or more diacritical marks should use the template:

{{R to diacritics}}

Any redirect title that contains one or more diacritical marks and redirects to the same title with no diacritical marks should use the template:

{{R from diacritic}}

With some article and redirect titles there may be the need to use a combination of the above templates, for example an article title that contains both an endash and one or more diacritical marks:

Janusz Radziwill (1612-55)Janusz Radziwiłł (1612–55)

...note that an ASCII hyphen (-) in the date span is redirected to a non-ASCII endash (–), and the final two letters in the surname are two ASCII letters that redirect to two diacritically marked letters (see "Bars/Strokes" below). Also, in the case of diacritical marks, both titles should otherwise be the same title except for very minor differences (such as the hyphen → endash in this example).
