Of course. But wchar_t* is not the only way to use Unicode in C. UTF-8 is the most common way to use Unicode in C in recent days. (except Java, .NET, and Windows API) So the importance of wchar_t* APIs are relative, not absolute. In other words, why don't we have an encode API with direct UTF-8 input? Is there any evidence wchar_t* is much more important than UTF-8? > 2.

I never said removing the wchar_t* member is motivation for PEP 624.
