Perl strings internally would have to be UTF8. Mandatory prerequisite would be normalize_charset 1 in SA. Could be some cases where SA can't decode mails properly to UTF8, so it's a question mark what happens then. Some changes are coming already in 4.0, for example normalize_charset 1 will be default. But more complex internal/rule changes require a lot of thought on how to maintain backwards compatibility. I'm sure some people will still run 3.4 for years to come. Sorry to say but there are too few developers right now. It's up to the community to pick up the pace.
