I noticed that HTTrack is rewriting:
   <meta charset="utf-8" />

With:
   <!-- Added by HTTrack --><meta http-equiv="content-type"
content="text/html;charset=utf-8" /><!-- /Added by HTTrack -->

This seems a shame since the shortened form is now part of the HTML5
standard.

It would be nice if HTTrack could recognize the shortened form and not rewrite
it!

Thanks
