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...

mb_strcut - Get part of string

SYNOPSIS
string mb_strcut (string $str, int $start, [int $length = NULL], [string $encoding = mb_internal_encoding()]) DESCRIPTION
mb_strcut(3) extracts a substring from a string similarly to mb_substr(3), but operates on bytes instead of characters. If the cut position happens to be between two bytes of a multi-byte character, the cut is performed starting from the first byte of that character. This is also the difference to the substr(3) function, which would simply cut the string between the bytes and thus result in a malformed byte sequence. PARAMETERS
o $str - The string being cut. o $start - Starting position in bytes. o $length - Length in bytes. If omitted or NULL is passed, extract all bytes to the end of the string. o $encoding -The $encoding parameter is the character encoding. If it is omitted, the internal character encoding value will be used. RETURN VALUES
mb_strcut(3) returns the portion of $str specified by the $start and $length parameters. SEE ALSO
mb_substr(3), mb_internal_encoding(3). PHP Documentation Group MB_STRCUT(3)
