If you got a warning like "Wide character in print...", this is a warning that happens in 5.8.x when the file handle you're printing to has not been set up to use unicode character semantics.

I don't recall off-hand why this warning matters (when I triggered the warning just now, the character still printed as intended). Look at the perlunicode and perluniintro man pages to get more info on this.

To avoid this warning, use the techniques described in the "PerlIO" man page, to open a file handle for ":utf8" i/o, or set the i/o protocol of an already-open file handle (like STDIN or STDOUT) to handle utf8 -- e.g.:

$_ = "\x{0411}\n"; # Cyrillic capital letter BE

binmode( STDOUT, ":utf8" );

print;  # Look, ma, no warning!
