Copy TCHAR* string from other thread - c

Question

I want to copy data from another thread to struct and print. _tpintf() doesnt show russian letters corret.
in concole I see this, but I expect to see "IN THREAD текст клиент1". Please explain why tchar doesnt work? Also I noticed that if I use _tcprintf, "клиент1" shows correct, but "текст" become wrong
Code of thread function which tries to copy data from another
static DWORD WINAPI StdinInfo(LPVOID param)
{
struct msg msg;
TCHAR buf[1280] = { 0 };
parameters* p = (parameters*)param;
while (TRUE)
{
_fgetts(buf, 1280, stdin);
while (_tcslen(buf) > 0 && buf[_tcslen(buf) - 1] == TEXT('\n'))
buf[_tcslen(buf) - 1] = TEXT('\0');
buf[128] = TEXT('\0');
if (!_tcscmp(buf, TEXT("stop")))
{
//printf("Terminating...\n");
msg.isEmpty = 0;
msg.type = STOP;
_tcscpy(msg.message, buf);
_tcscpy(msg.nickName, p->nickName);
SendMessage(p, &msg);
break;
}
else if (!_tcscmp(buf, TEXT("exit")))
{
msg.isEmpty = 0;
msg.type = DISCONNECT;
_tcscpy(msg.message, buf);
_tcscpy(msg.nickName, p->nickName);
SendMessage(p, &msg);
break;
}
msg.isEmpty = 0;
msg.type = MESSAGE;
_tcscpy(msg.message, buf);
_tcscpy(msg.nickName, p->nickName);
_tprintf(TEXT(" IN TREAD %s %s\n"), msg.message, p->nickName);
SendMessage(p, &msg);
}
return 0;
}
