Subject: More problems with rules and Charset for french language

Hi,...

I am trying to guest the second half of a LM hash.
The password contains french characters.
I know some characters. For example,
First character   : S
Second character  : T
Third character   : R
Forth character   : unknow
Fifth character   : unknow
Sixth character   : O
Seventh character : R


I build the john.ini with the following instructions,


##################################################################
# A cracker for some FRENCH characters
##################################################################

[Incremental:french]
File = french.chr
MaxLen = 7

[List.External:french]
int length;

void init()
{
	word[0] = 0x20 - 1;		// Start with " "
	word[length = 1] = 0;
}

void filter()
{
	word[6] = 'R';
	word[5] = 'O';
	word[4] = word[1];
	word[3] = word[0];
	word[2] = 'R';
	word[1] = 'T';
	word[0] = 'S';
}


void generate()
{
	int i;

	i = length - 1;			// Start from the last character
	while (++word[i] > 0xff)	// Try to increase it
	if (i)				// Overflow here, any more positions?
		word[i--] = 0x20;	// Yes, move to the left, and repeat
	else				// No
	if (length < 8) {
		word[i = ++length] = 0;	// Switch to the next length
		while (i--)
			word[i] = 0x20;
		return;
	} else {
		word = 0; return;	// We're done
	}
}

***************************************************************************

But when I tray to use this external mode I obtain this message,

C:\john\john-test-03>john --external=french hash-pims.txt

Why always john tray always the same pass "STRTTOR" ?
Why he never stop ?
