Thank you, that's nice.  Oh, well, for the non-Perlmaniacs it might be
confusing that two functions are called after the other, and hard to
understand that print just prints the result of the pack or unpack
function.  Is

perl -ne 'print(pack "u", $_);' 

better (and actually works always, not only with my test file)?
