Can you guarantee that on some audited system that runs an Internet
service that is used by people from all over the world and they were
using different operating systems, they speak different languages and
still all passwords have just one encoding? It could be true today. But
was it true in the past?
For systems with mixed encodings old jumbo would crack all encodings
using e.g. all.lst on one run. New jumbo will need several runs and all
e.g. ASCII-only passwords will be repeated.
But if this is a problem of the past, let's leave it in the past.
