Why would this be intentional?
One concern I have about this approach is that I am guessing that the
current implementation of str_tolower() is a lot slower than the
current implementation of downcase_truncate_identifier(). It would be
nice to have an implementation that is capable of handling wide
characters but doesn't actually incur the speed penalty unless a wide
character is actually present.
