Source separation rule also for the 8859 series of standards gives that
they had to be separately encoded.
But even so, they had to be separated: similar-looking uppercase forms
have different corresponding lowercase forms. So as not to make case
mapping horribly difficult (it's hard enough as it is!), Latin, Greek,
and Cyrillic had to be non-unified.
