char type conversions in c++
#include <iostream>
#include <locale>
#include <string>
#include <fstream>
#include <codecvt>
// utf8/utf16/utf32 can be directly written to file without conversions
// sizeof(T) gives you bytes of the type
// .size() .length() gives count of chars
// if char16_t is stored the open the file with utf16 encoding
