Maybe we should implement a strategy so that the resulting IRI is first evaluated and then if an exception occurs, the string is URL-encoded in some way. However, this should already be happening in the Triplifier, so the problem may be limited to the HTML Triplifier using his own URI building code.

Maybe this is not still the case? @enridaga, do you remember the webpage raising the error?
