Obviously YAML::XS doesn't do that either.

But aside from that I agree with you, that something ist broken in
F(ast)CGI. It seems more that F(ast)CGI pays attention to the utf8 flag
where it shouldn't, because it seems to automatically utf8::encode the
buffer due to the set utf8 flag.

No, it is not. Because it claims:

  This module exports the functions Dump and Load. These functions are
  intended to work exactly like YAML.pm's corresponding functions.

And that's not the case. And therefore you can't use it as a
drop-in-replacement for other YAML modules.
