            Bug ID: 28643
           Summary: it_IT: Days and Months do not have an uppercase letter
           Product: glibc
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: localedata
          Assignee: unassigned at sourceware dot org
          Reporter: saloniamatteo at protonmail dot com

it_IT patch

Greetings,
I have noticed glibc's it_IT locale has quite a few mistakes:

-   Abbreviated and Full week days (e.g. Monday/Lunedì) do not have a capital
letter (should be Lunedì but it is lunedì)
-   Abbreviated and Full months have the same problem as above, e.g. gennaio
should be Gennaio
-   Language name (lang_name) still has the same problem as above (italiano
instead of Italiano)

This bug is not present in other locales, as far as I know.
Latest source check date: 02/12/2021 @ 10:45
Version found in version.h: "2.34.9000" (development)

I have made the following patch: fix-italian.patch (you can find it in the
attachments)

They are not capitalized in CLDR either:

https://github.com/unicode-org/cldr/blob/main/common/main/it.xml#L1848
        <dayWidth type="wide">
                <day type="sun">domenica</day>
                <day type="mon">lunedì</day>
                <day type="tue">martedì</day>
                <day type="wed">mercoledì</day>
                <day type="thu">giovedì</day>
                <day type="fri">venerdì</day>
                <day type="sat">sabato</day>
        </dayWidth>

As far as I know, the capitalization of these words in Italian depends on
whether they appear at the beginning of a sentence or not.

    Gennaio è il primo mese dell'anno.
    Oggi è lunedì.
    L'italiano è una lingua bellissima.

So if they are usually not capitalized but only at the beginning of sentences,
then maybe the application using this data should
do the capitalization?

For example, maybe `cal` should capitalize here because these names appear "at
the beginning"?:

$ LC_ALL=it_IT.UTF-8 cal 
    novembre 2023   
lu ma me gi ve sa do
       1  2  3  4  5
 6  7  8  9 10 11 12
13 14 15 16 17 18 19
20 21 22 23 24 25 26
27 28 29 30

On the other hand, maybe almost all uses of this data in glibc are not within a
sentence, so maybe capitalizing always is OK?


> This bug is not present in other locales, as far as I know.

Currently many locales don’t have these capitalized:

glibc/localedata/locales (master $)
$ grep day  fr_FR es_ES
fr_FR:abday   "dim.";"lun.";"mar.";"mer.";"jeu.";"ven.";"sam."
fr_FR:day     "dimanche";/
fr_FR:first_weekday 2
es_ES:abday   "dom";"lun";/
es_ES:day     "domingo";/
es_ES:first_weekday   2

As we want to keep this in sync with CLDR, we should use the capitalization as
it is used in CLDR, i.e. these should be capitalized in the glibc locales only
if they are always capitalized (like they are in English or German). If they
are only capitalized when at the beginning of a sentence or when used
stand-alone, the application (like "cal" in the above example) should do the
capitalization.
