According to http://perldoc.perl.org/perlrun.html , you probably need -Mstrict
and -Mutf8 instead of the lowercase -m, so "sub import" will get called:

shlomif@telaviv1:~$ perl -Mstrict -Mutf8 -le 'my $char="汉语"; print "it is
chinese" if $char =~ /\p{Han}+/'
it is chinese
shlomif@telaviv1:~$

HTH,
