Maybe the confusion here is just that you are thinking that this string consists of 3 bytes, while it (probably) is at least 6 bytes long:
See here (hexdump):

Code:

echo -n ąąą | xxd -g 1
0000000: c4 85 c4 85 c4 85

So a mask of length 3 is too short for a password of length 6, as simple as that.

(note: not sure if the bytes mentioned above are correct, that depends on the encoding!)
