This is expected behaviour. In the absence of a "setlocale" call the
program's locale is C. To use the locale settings from the environment,
call setlocale(LC_ALL, ""). Observe:
$ locale
LANG=fi_FI
LC_CTYPE="fi_FI"
LC_NUMERIC="fi_FI"
LC_TIME="fi_FI"
LC_COLLATE="fi_FI"
LC_MONETARY="fi_FI"
LC_MESSAGES="fi_FI"
LC_ALL=
$ cat try-orig.c
#include <ctype.h>
#include <stdio.h>
int main()
{
int c = '�';
printf("%c: %d\n", c, isprint(c));
return 0;
}
$ gcc try-orig.c -o try-orig -Wall
$ ./try-orig
�: 0
$ cat try.c
#include <ctype.h>
#include <locale.h>
#include <stdio.h>
int main()
{
int c = '�';
setlocale(LC_ALL, "");
printf("%c: %d\n", c, isprint(c));
return 0;
}
$ gcc try.c -o try -Wall
$ ./try
�: 16384
$
This behaviour is (AFAIK) described in the ISO C standards, and in the
setlocale(3) manual page.
To the maintainer: you may close this bug.
