Description Karl Williamson 2016-08-12 01:09:44 UTC
Some of the locale definitions that come with 10.3 have defects.  These include:
[:lower:] matches 0xDF but [:alpha:]) doesn't with locales
 'lt_LT.ISO8859-13'
 'lv_LV.ISO8859-13'  

0xBD should be [:upper:] but isn't in 'lv_LV.ISO8859-13'  

In case you are not aware of it, you can pretty much get out of the business of supporting UTF-8 locale definitions by using the freely available POSIX ones supplied by Unicode.  The recent releases, you have to generate them yourself from the CLDR DB.  I can't seem to find the link to the tool that does it, just now.

Earlier versions had them pre-computed:

This should be fixed in FreeBSD 11 where they have been completly reworked (unfortunately it won't be mergeable on 10) can you confirm?

(In reply to Baptiste Daroussin from comment #1)

Yes, these are no longer showing as bugs.

However, the UTF-8 locales in this release show some collation weirdness for some controls.  If we actually find this is a probable bug, we will file a new bug report

Yes there is a bug, I will request and errata for, don't know if that fixes the one you found, but I will merge my fixes in 11-STABLE next week and request en errata

Looking at the UnicodeData.txt, 0xbd is "VULGAR FRACTION ONE HALF", are sure it should be "upper"?

This bug is about Lithuanian locales where 0xBD is not the same as it is in Unicode
Comment 6 Yuri Pankov freebsd_committer 2018-11-15 20:12:19 UTC
(a bit of ugly code)

$ cat t.c
#include <err.h>
#include <locale.h>
#include <stdio.h>
#include <stdlib.h>
#include <wchar.h>

int
main(void)
{
        char mbc[] = { 0xBD };
        wchar_t wc;

        if (setlocale(LC_ALL, "lv_LV.ISO8859-13") == NULL)
                err(1, "setlocale");
        if (mbtowc(&wc, mbc, 1) == -1)
                err(1, "mbtowc");
        printf("%#x\n", wc);

        return (0);
}
$ cc -o t t.c
$ ./t
0xbd

So it looks like it *is* the same.  What character did you mean exactly?
Comment 7 Yuri Pankov freebsd_committer 2018-11-15 20:32:32 UTC
OK, sorry, I'm really starting to forget what single byte locales are, and that this code isn't applicable here.  But, luckily for me, ISO8859-13 charmap shows that 0xBD maps to 0x00BD wide character.
