+>>===== DESCRIPTION =====>>
+Per the CSL documentation (link below), dashes are standardized for page ranges
+but not everything with a dash is a valid page range. Valid page ranges are
+numbers with the same or no prefix.
+
+For example, 110–115 and N110–N115 are valid page ranges but 110-N6 is not and
+thus retains its original dash character.
