They are not talking about ANSI strings (they are not Unicode
compatibles) but UTF-8 strings. So the choose is UTF8 or UTF16 (or
UCS32 of course) and in Windows UTF16 is faster as do not need
conversion to call the API, zero time against any amount of time. Of
course in other OS the things changes.
