After a category rename

I've moved Category:People from Salem to Category:People from Salem, Tamil Nadu. I'm not sure if it's better to delete the original category or to populate it with Category:People from Salem, Massachusetts, Category:People from Salem, Oregon, etc. Clarityfiend (talk) 02:03, 7 February 2015 (UTC)

@Clarityfiend: This is the sort of thing that WP:CFR exists for. Indeed, you should have announced it there before moving the category page, even for a clear-cut C2 speedy rename. --Redrose64 (talk) 13:02, 7 February 2015 (UTC)

How to create a category

I want to add a category Sindhi-language television channels in Pakistan‎ kindly help me how to create category ?--Jogi don (talk) 05:12, 8 July 2015 (UTC)

(Months too late) Wikipedia:Categorization#Creating category pages explains how to do this. -- John of Reading (talk) 06:51, 24 February 2016 (UTC)

Me too please! Is there a policy that governs creation of categories? Can I search to see if a given category already exists?Feldercarb (talk) 22:19, 23 February 2016 (UTC)

@Feldercarb: I haven't created many categories myself, but if you look through Wikipedia:Categorization you'll have a better idea of what is usual. To search, go to Special:Search, choose "Advanced" and then tick the "Category" namespace. -- John of Reading (talk) 06:51, 24 February 2016 (UTC)

ok

I would like to add a photo Whycantuc (talk) 04:31, 23 February 2016 (UTC)

@Whycantuc: You're at the wrong page. I think you need to read Help:Introduction to uploading images; if that's not what you mean, try asking at WP:HD. --Redrose64 (talk) 19:57, 23 February 2016 (UTC)

Sub categories

How do you make sub categories??? 192.199.53.2 (talk) 19:55, 28 February 2016 (UTC)

If you want to do this yourself, you'll need to register an account and then follow the instructions at Wikipedia:Categorization#Creating category pages. You can also request that someone else makes the sub-category for you by visiting Wikipedia:Article wizard/Category. -- John of Reading (talk) 20:19, 28 February 2016 (UTC)

No diacritics in "defaultsort"?

Hi. I just noticed at Manuel Escórcio that de "DEFAULTSORT" is "DEFAULTSORT:Escorcio, Manuel", without the diacritic (accent mark) over the first "o". So I checked a few other names with diacritics, Lourenço (given name), "DEFAULTSORT:Lourenco (given name)" and Diogo Cão, "DEFAULTSORT:Cao, Diogo" and none Has diacritics in the DEFAULTSORT. So I presume that it is so for a reason. But, were I or anyone else unwittingly add the diacritic (making it Escório, Lourenço or Cão), what would happen? Rui ''Gabriel'' Correia (talk) 13:06, 9 March 2016 (UTC)

Re. "what would happen": usually within some days a bot passes by and removes the diacritics.

Example: adding category with an ö in the sort key → next day: a bot sorts it out --Francis Schonken (talk) 18:15, 9 March 2016 (UTC)

Re. "for a reason": the reason is the alphabetic sorting (collation) of names in categories: e.g. "Ciao" would be sorted before Cão in an automatically sorted category list, where the order, when trying to find the name, is better Cão and then Ciao. Removing the diacritic for sorting handles that. --Francis Schonken (talk) 13:40, 9 March 2016 (UTC)

@Rui Gabriel Correia: See WP:SORTKEY, paragraph beginning "Because the software uses an imperfect computer sorting ..." --Redrose64 (talk) 18:50, 9 March 2016 (UTC)

Thanks, Francis Schonken and Redrose64. Really appreciated. Seldom does one get replies that fully answer the question, such that there is not even a chance of a "yes, but what if ...". Small things like this renew one's hope in the project (comment aimed primarily at the Portuguese Wikipedia). Rui ''Gabriel'' Correia (talk) 22:27, 9 March 2016 (UTC)

Passing a category by parameter

Is this meant to be parsing? JennyOz (talk) 02:31, 8 April 2016 (UTC)

@JennyOz: I think "passing" is correct. I've reworded the sub-heading - is that clearer? -- John of Reading (talk) 05:48, 8 April 2016 (UTC)

More on diacritics

From the article:

...MediaWiki groups accented characters separately from their unaccented version, so pages starting by À, Á, Ä, will be listed under separate headings, instead of under heading A.

This doesn't seem to be the case. It's hard to impossible to find an example in enwiki (because all pages with special characters have a DEFAULSORT with no special characters) but there are plenty of examples in other wikipedias. From ptwiki: pt:Ü shows in category pt:category:Alfabeto latino under the normal U, without creating any special heading.

Note: To confuse matters some more, there are some special letters in that same category that create a heading. That is expected and documented in (WP:SORTKEY).

Aisteco (talk) 00:13, 13 April 2016 (UTC)

I believe that each different language has its own locally-configurable sort order. As an example, the Swedish language has an alphabet of 29 letters, ending with X, Y, Z, Å, Ä, Ö, so at Swedish Wikipedia, pages whose names begin with those three extra letters sort after Z, see Kategori:Svenska efternamn; however in the French language, there are 26 letters - Ä and Ö are not considered separate letters but accented versions of A and O, so they sort with A and O. --Redrose64 (talk) 09:10, 13 April 2016 (UTC)
