Bug#495494: nl_langinfo() returns ANSI_X3.4-1968 instead of UTF-8

["Joe Nahmias" <joe@nahmias.net>]

Package: libc6-i686
Version: 2.7-13
Severity: normal

Hello,

It seems my machine can't make up its mind as to what charset is being used.
Most things seem convinced that it is UTF-8:

$ grep -v ^# /etc/locale.gen | grep -v ^$
en_US.UTF-8 UTF-8
$ grep -v ^# /etc/default/locale | grep -v ^$
LANG=en_US.UTF-8
$ locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE=C
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=
$ locale charmap
UTF-8
$ localedef --list-archive
en_US.utf8


However, nl_langinfo(CODESET) returns ANSI_X3.4-1968:


$ cat test.c
#include <stdio.h>
#include <langinfo.h>

int main(int argc, char *argv[])
{
  printf("%s\n", nl_langinfo(CODESET));
  return 0;
}
$ gcc test.c -o test
$ ./test
ANSI_X3.4-1968


Why would nl_langinfo() be different than everything else and how can I
fix this?  Note that the manpage specifies that it should return the same
string as `locale charmap` -- that is obviously not the case here.

Thanks,
--Joe
