[cl-wiki-devel] Encoding question and a patch

[Vehbi Sinan Tunalioglu]

It works!!!

No need for:
<meta http-equiv="Content-type" content="text/html; charset=UTF-8" />
Since the http body content is already is marked as utf8 in header...

I just changed (esc content) to (str (escape-for-html content))

Thanks...
