it's not funny business, but rather the results from a typical use of warnings:

$ perl -e 'use warnings; print "\x{B514}\x{C790}\x{C778} \x{BA85}\x{D568}"'
Wide character in print at -e line 1.
...

no warnings qw(utf8) gets rid of it, but the warnings pragma isn't supposed
to work at a distance like we want it to.  you might try

  local $^W=0;

but that will suppress all warnings, not just the utf8 ones, which is kinda
against the point if you care about these kind of things.
