所有其他答案似乎都是为了直接代码点翻译(即等价物 (wchar_t)c 对于每一个 char c 在字符串)。这可能不适用于所有地区,但如果是,它将起作用。您的 char 是ASCII或拉丁语-1和你的 wchar_t 是unicode。如果你确定这是你真正想要的,那么最快的方式实际上是避免完全转换,并使用 std::lexicographical_compare:...

Although it pretends to support both wchar_t and char it's slightly broken. The _T macro that may or may not put the L in front of string literals is even more broken. As you're developing on Windows then just use wchar_t (and tell MSVC to define it as a base type, not a type...
