String DAX Data type


Every string in DAX is stored as a Unicode (UTF-16) string, where each character is stored in at least 16 bits (2 bytes). By default, the comparison between strings is case-insensitive and accent-sensitive, so the two strings “Report” and “REPORT” are considered equal, whereas “e” and “è” are considered different.
