That will not work. It will print the pointer to the string as hex, not the string itself.

How about this:

Code:
{
  const char *str="asdf";
  int n;
  for(n=0; str[n] != '\0'; n++)
    printf("%02x",(unsigned char)str[n]);
}

Given the weird characters in the string you want, you may have encoding problems that make the bytes different while the string looks the same. I can't even copy-paste that string. It messes up my shell.

[edit] Nope, that doesn't work. Your string contains a NULL. Either that or it's unicode... working on it...
