Summary: A FNC_1 character inside the barcode gives an error

Initial Comment:
Hi,

If you have a FNC_1 character somewhere inside a 
code128 barcode, you will in some cases eventually get 
an ArrayIndexOutOfBoundsException. This is because 
Character.digit gives -1 as result of this character in 
row 218 in DefaultCode128Encoder.java. If the value 
next to the FNC_1 character is 0, then encoded[respos] 
will be -1 and this is the thing that later gives the 
exception.

My barcode example:
ñ020456789012341837100ñ3101000200, where ñ is the 
FNC_1 character.

I think I have been able to fix the bug. It's fixed in 
Barcode4J's CVS repository. Please be aware that the krysalis-
barcode CVS module is frozen. See 
http://sourceforge.net/projects/barcode4j/. I still hope I can 
find the time soon to do another beta before finally releasing 
1.0 final.

Thanks for spotting this. It's not the zero after FNC_1 that is 
the problem. It's the FNC_1 in the second position of a would-
be duo of digits encoded in codeset C. The algorithm fails to 
handle the FNC_1 character in all situations. I've started 
fixing the algorithm but haven't succeeded in all situations, 
yet. I'll try again later as soon as I have more time (probably 
on Friday).
