>Why have a dedicated function for 2 lines of code? Then why does std::max() exist? >People will use the generalized tolower for UTF8 encoded in narrow strings and have issues. tolower() and toupper() work correctly on UTF-8 strings, because UTF-8 was specifically designed so that non-ASCII characters were represented by sequences of purely non-ASCII bytes. >Generalized string conversion is a very complex Hence why people who say C++ should have a tolower() that operates on strings are not asking more complex Unicode support.
