Wait three months for a journal entry and then two come along at once.
I've been playing a lot with UTF8 and the UTF8 flag a lot recently and I ended up creating This script that creates this list of what happens when you toggle on and off the UTF8 flag for various bytes, print the output to a utf8 filehandle and Devel::Peek Dump the scalar to see what Perl is actually storing. Fun huh?
And your journal entry title nicely shows up a bug in use.perl (or possibly the version of perl that it's running on) - the recent journals entry on the front page shows the bytes making up the utf8, rather than the Unicode characters
