Hi,
First, sorry about the noise: I had failed to activate your symbols as
TODO keywords. Now I do reproduce your results.
It also doesn't seem to help to add your special characters to Emacs
word syntax, as the FAQ says you should.

I think there's a bug in org-html.el (org-export-as-html), around line
1611. A function that is meant to get a valid class name for the todo
keyword is not called when the class attribute of the span tag is
inserted, but a line below, where the visible text content of the
span tag is inserted. I'm posting a patch.
Yours,
Christian
