__NOTOC__
=== Usage ===
{{hatnote|Use this rcat template in '''any [[wp:namespace|namespace]]'''.}}
* This redirect category ([[WP:RCAT|rcat]]) template populates both {{Cat|Redirects from titles without diacritics}} and {{Cat|Unprintworthy redirects}}.  In 2003, efforts were begun to support the [[Wikimedia Foundation]]'s goal of increasing access and availability of  ''Wikipedia'' articles in {{diff|Wikipedia:Pushing to 1.0||1319195|printed versions}}.  Redirect titles without diacritical marks are not suitable for a printed version.  In other words they are [[WP:Printworthiness|unprintworthy]].
{{info|image=Stop hand nuvola.svg|Please do not alter the printworthy settings of this rcat without first notifying the '''[[WP:Version 1.0 Editorial Team|Version 1.0 Editorial Team]]''', who are responsible for any and all materials, including redirects, that go into a printed version of ''Wikipedia''.}}
* Add this rcat to a redirect in the following manner: 
<syntaxhighlight lang="wikitext">
#REDIRECT [[(target page name)]]

{{Rcat shell|
{{R to diacritic}}
}}
</syntaxhighlight>
: and ''when the redirect is in article mainspace'', printworthiness should also be tagged:
<syntaxhighlight lang="wikitext">
#REDIRECT [[(target page name)]]

{{Rcat shell|
{{R to diacritic}}
{{R unprintworthy}}
}}
</syntaxhighlight>
: Template {{tl|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:
<syntaxhighlight lang="wikitext">
#REDIRECT [[(target page name)]]

{{R to diacritic}}
</syntaxhighlight>
: This is in accord with instructions found at [[Wikipedia:REDCAT]].
* Use this rcat to tag any redirect in any namespace with '''''no'' [[diacritical mark]]s''' (accents, umlauts, etc.) to essentially the same page name that '''''does''''' have diacritical marks.
* This rcat template {{em|must not}} be used to tag redirects to a title with differences that are 1: [[Typographic ligature|ligatures]] (like æ and Œ – use {{tl|R to ligature}} instead), or 2: other [[ASCII|non-ASCII]] characters that {{em|do not include}} diacritics (like [[Greek alphabet|Greek letters]] – use {{tl|R from ASCII-only}} instead).

==Explanation==
{{wiktionarypar|ASCII}}
{{wiktionarypar|diacritic|diacritical|diacritical mark}}
[[File:USASCII code chart.png|thumb|300px|ASCII chart from [[MIL-STD-188#MIL-STD-188-100_series|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. [[Diacritic|Accents]] and [[Trema (diacritic)|umlauts]] are examples of diacritical marks. Conversely, [[Typographic ligature|ligature]]s and standard [[Greek letter]]s 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 [[WP:MOVE|moved]] to that name. For the titles that properly do and should use special characters and diacritics per [[Wikipedia:Naming conventions (use English)|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:
:{{tlx|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:
:{{tlx|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:
:{{tlx|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:
:{{tlx|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:
* {{-r|Janusz Radziwill (1612-55)}}[[File:Redirect arrow without text.svg|35px]][[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 "[[Bar (diacritic)|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).

===Examples of non-diacritical, non-ASCII characters===
(This is not a comprehensive list)

[[Typographic ligature|Ligatures]]: <big>[[Æ]] æ [[Œ]] œ<br/>
</big>Letters that seem like diacritics: <big>[[Ø]] ø  [[Ð]] ð</big><br/>
Others: <big>[[Ə]] ə [[Þ]] þ </big>

Standard [[alphabetic]]al letters are usually non-diacritical. See [[List of writing systems]] for more information.

The standard [[Greek alphabet]] is non-diacritical, though there do exist [[Greek diacritics|Greek letters with diacritical marks]].<br/><big>Γ Δ Θ Λ Ξ Π Σ Φ Ψ Ω α β γ δ ε ζ η θ ι κ λ μ ν ξ ο π ρ ς σ τ υ φ χ ψ ω</big>

===Other tips===
Most titles in violation of the [[Wikipedia:Naming conventions#Special characters]] are northern European in origin, and have long established transliterative English equivalents.
