Yes, this is a bug in the grok2html script. A year ago I was using
`identical` code to render rest text fils to html using zpt's and had
unicode rendering well when reading the file with codecs. I have tried
to remedy the problem in the current grok2html script but failed. I
think the solution lies in the class ReStructuredTextToHTMLRenderer,
particularly the `render` method. Perhaps a dig in ZopeTranslator would
show up a solution.

Sorry I can't be more helpful at the moment.

Best regards,
Darryl
