It is clearer now: the existing filters in the reporters only filter out static chars and should also filter out the configured per-reporter delimiter. All reporters could have a default filtering implementation that filter out the configured delimiter and some reporters could override this implementation to filter out other characters in addition to the delimiter was (Author: echauchot): Hi [~chesnay], thanks for your answers.
