problems with unicode chars

[haf@…]

Using unicode chars, the feature does reply with an overall error (see below). In an existing page this is a show-stopper, because the error does not point to the page or char which is malicious. How can I find out which one is the bad unicode character to remove it eventually? Or could unicode support be added to the feature?

I had the same issue. Fixed it in a non-elegant way, but this ticket has 5 years open so that'll have to do.
