ColdFusion MX: ColdFusion now supports the Java UCS-2 representation of Unicode character values 0–65535. (Earlier releases supported ASCII values.)
String-processing functions process any of these characters (including ASCII 0 (NUL) characters), and continue counting subsequent characters of the string, if any. (In earlier releases, some string-processing functions processed the ASCII 0 (NUL) character, but did not process subsequent characters of the string.)
