Yes, the size of wchar_t is implementation-dependent, so it's not formally broken. But the Windows implementation is technically broken, as the programmer can neither rely on the assumption, that any given character can be stored into a wchar_t, nor that iterating over a string will correctly return the stored characters, nor that insert/erase/substring operations will cut the string properly - which completely defies the purpose of wchar_t. If i have to code multi-byte awareness into each and every string operation anyways, there is no point of using wstring instead of string and the much more common UTF8 encoding. And it is getting even worse, as many Windows libraries and Windows applications are not aware of the fact, that a Windows wstring is supposed to be UTF16. The code is assuming one codepoint per string position and fails in an unpredictable way, if the input data acutally contains codepoints from the upper pages. >> On most modern systems, wchar_t matches char32_t. >> But it is not a requirement. > > That was where David is wrong. He's not.
