Since 5.36 is meant to turn on warnings, this will be explicitly wrong, not
subtly.
Perhaps the "wide character" warning is too unclear, but we can always
improve the text to include a doc link as such.
What compels me more is the following example.
Let's say I'm looking for customers in my database named josé. Easy, I'll
use DBIC:
$customer_rs->search({ name => 'josé' })
But when I run it, I get nothing. That's because the various DBDs will
handle encoding and decoding for you, bc perl is meant to deal with text in
userland.
Had utf8 been turned on, then I would've started with text, not bytes, and
found my customers instead of mojibake (though on the other hand, the non
utf8 is a great way to find double encoded text).
I think this is a more realistic example than printing a string literal,
where the behavior is surprising and conceptually inconsistent.
