There is no readily available, verifiable encyclopedic information on an individual or concept named “Charles N. Riotte.” Searches of major biographical databases, academic publications, and reputable historical records do not yield a recognized figure or widely documented entity by this name. Consequently, the term is not widely recognized in established reference works.
Given the lack of reliable sources, further detailed discussion cannot be provided without venturing into speculation. Should additional, verifiable information become available from reputable encyclopedic or scholarly sources, a more comprehensive entry could be drafted.
