History
ColdFusion MX: Changed Unicode support: ColdFusion supports the Java UCS-2 representation of Unicode character values 0-65535. (ColdFusion 5 and earlier releases supported ASCII values 1-255. When calculating a length, some string-processing functions processed the ASCII 0 (NUL) character, but did not process subsequent characters of the string.)
