Package: libc6
Version: 2.10.1-3
Severity: normal
With a ja_JP.UTF8 locale defined, the program foo.c below prints
E3 80 87 00 E4 B8 80 00 E4 BA 8C 00
where I expected the 00 null bytes to be semi-colons, separating the
symbols for the alt digits, per POSIX
http://www.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap07.html#tag_07_03_05_02
which says
The value consists of semicolon-separated symbols.
(Semi-colon is also the separator in the locale definition file, but
that's a separate thing. That chapter of the spec has separate sections
for the file format and the subsequent C-language access.)
I believe the same problem is present in nl_langinfo(ERA). The spec is
"Era description segments are separated by semicolons", but the libc
code ends up giving '\0' separators.
#include <stdio.h>
#include <stdlib.h>
#include <locale.h>
#include <langinfo.h>
int
main (void)
{
char *s;
int i;
const char *locale = "ja_JP.UTF8";
if (setlocale (LC_ALL, locale) == NULL) {
printf ("no locale %s\n", locale);
exit (1);
}
s = nl_langinfo (ALT_DIGITS);
/* printf ("ALT_DIGITS `%s'\n", s); */
for (i = 0; i < 12; i++) {
printf (" %02X", (int) (unsigned char) s[i]);
}
printf ("\n");
return 0;
}
