To expand a little on what
fishbot_v2 said; you need to make sure you text is in utf-8, and that perl knows that it's utf-8 encoded. You can use the
Encode module to do that, after that ord() will work as you expect it.
Also note that if you just want a valid HTML output, and your text is already utf-8 encoded, you can specify the utf-8 charset in your html page and then you don't need to use the &#number; encoding. This is also more efficient in terms of file-size.
You can set the charset in your content-type header (either generate the content-type "text/html; charset=utf-8" from a script or configure the webserver to send that content-type for static html files), or you can use the following meta-tag in your HTML head:
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=utf-8">
Ps/update: if you want to work with unicode / utf-8 text, you should use a recent perl version (5.8.0 or higher if you can get it); unicode handling has improved a lot in the last releases.
