----------------------------------------
Sample exception we might get trying to serialize such a "corrupted" literal as
RDF/XML:

> Project: Stanbol
> Issue Type: Bug
> Reporter: Olivier Grisel
> Assignee: Olivier Grisel
>
> Some text to analyse might contain control chars such as "\x13", "\x14",
> "\x15"... Such characters cannothe be serialized as XML and are generally
> worthless in the labels and context properties of enhancements.
> The NER engine should filter them out before writing its annotations to the
> content item graph.
