Bug #: 14257
Summary: setlocale(LC_CTYPE, NULL) causes undesired side
effects
Product: glibc
Version: 2.14
Status: NEW
Severity: normal
Priority: P2
Component: localedata
AssignedTo: unassigned@sourceware.org
ReportedBy: siteshwar@gmail.com
CC: libc-locales@sources.redhat.com
Classification: Unclassified
I have written following program to reproduce side effect :
#include <stdio.h>
#include <wchar.h>
#include <locale.h>
int main()
{
setlocale(LC_ALL,"");
//This will cause side effect
const char * c = setlocale(LC_CTYPE, NULL);
printf("%s\n", c);
while (!feof(stdin))
{
wint_t t = fgetwc(stdin);
wchar_t t1 = static_cast<wchar_t>(t);
putwc(t1, stdout);
}
}
When I try to input unicode characters I get garbage characters in output.
[situ@juggernaut bugs]$ ./a.out
测试
K�
If I remove call to setlocale(LC_CTYPE, NULL) output is fine.
[situ@juggernaut bugs]$ ./a.out

This has nothing to do with setlocale. You are mixing char with wide char I/O
on the same stream (printf vs. putwc). The first output makes the orientation
permanent until the stream is closed.
