Ok, I'm not an utf8 expert. But I never "use utf8" in my unicode
applications and if i always encode and decode the data correctly everything
is fine.
I'm pretty sure I've read somewhere that you just need the "use utf8" pragma
if you have utf8 characters in variables names. I don't remember where it
was so i can't say if it's correct.
