I haven't looked at either implementation, but on ASCII everything is really simple.. isalpha, isdigit, isupper and islower are just a simple checks if the value is between two values, tolower(dchar c) is just return isupper(c) ? c+32 : c; etc. For Unicode this is most probably *much* harder (=> more expensive).
