I guess I was a little premature with this conclusion.

Here's a little test program:

------------------------------------------------------
#include <ctype.h>
#include <stdio.h>
#include <string.h>
#include <locale.h>

int main(void)
{
  setlocale(LC_ALL, "");
  const char *s = "aAbBcC äÄöÖüÜ sSß +-.,;:*!'|/";
  char buf[1000]; 
  const char *p = s;
  while (*p) {
        char b[10];
        b[0] = *p;
        b[1] = 0;
        strxfrm(buf, b, sizeof(buf));
        printf("%c ", *p);
        char *q = buf;
        while (*q) {
              printf(" %02X", (unsigned char)*q);
              q++;
              }
        p++;
        printf("\n");
        }
  return 0;
}
------------------------------------------------------

If I do

  export LC_COLLATE=de_DE

and then run it I get

a  0C 01 02 01 02
A  0C 01 02 01 04
b  0D 01 02 01 02
B  0D 01 02 01 04
c  0E 01 02 01 02
C  0E 01 02 01 04
   01 01 01 01 11
ä  0C 01 0B 01 02
Ä  0C 01 0B 01 04
ö  1A 01 0B 01 02
Ö  1A 01 0B 01 04
ü  20 01 0B 01 02
Ü  20 01 0B 01 04
   01 01 01 01 11
s  1E 01 02 01 02
S  1E 01 02 01 04
ß  1E 1E 01 04 04 01 02 02
   01 01 01 01 11
+  01 01 01 01 3A
-  01 01 01 01 15
.  01 01 01 01 1E
,  01 01 01 01 16
;  01 01 01 01 17
:  01 01 01 01 18
*  01 01 01 01 35
!  01 01 01 01 19
'  01 01 01 01 21
|  01 01 01 01 0D
/  01 01 01 01 1D

which would indicate that strxfrm() _does_ distinguish between
the various special characters.

Maybe the problem is actually somewhere else.

@Hermann: can you please try again, with the original VDR code,
but this time replace the strcasecmp() call in cRecording::operator<()
with strcmp()? Does it still work as expected?

Klaus
