Hi Uli,
kannst Du diesen alten Patch bitte nach 2.1.3 tun:
1998-10-19 Ulrich Drepper <drepper@cygnus.com>
* locale/C-ctype.c (_nl_C_LC_CTYPE_class): Clear ISCNTRL bit for
character >= 0x80.
(_nl_C_LC_CTYPE_class32): Likewise.
Reported by HJ Lu.
Damit sollte der Bug gefixt sein.
Danke,
Andreas

>Description:
iscntrl() does not identify characters in the rang 0x80-0x8f (and maby more) as control characters. The result is that gnome-terminal & xterm respond to shift-in and shift-out and other control characters with the high bit set, producing an unreadable display or other undesirable results.
>How-To-Repeat:
In a gnome-terminal or xterm run this program:
#include <stdlib.h>
#include <stdio.h>
int main(int argc, char *argv[], char *envp[])
{
int i;
for (i=0;i<=255;i++)
{
if (iscntrl(i))
printf("%02x %c is a control char \n",i,i);
else
printf("%02x %c is not a control char \n",i,i);
};
