std :: wstring VS std :: string

问题：

I am not able to understand the differences between std::string and std::wstring . 我无法理解std::string和std::wstring之间的区别。 I know wstring supports wide characters such as Unicode characters. 我知道wstring支持宽字符，例如Unicode字符。 I have got the following questions: 我有以下问题：

1. When should I use std::wstring over std::string ? 什么时候应该在std::string使用std::wstring ？
2. Can std::string hold the entire ASCII character set, including the special characters? std::string容纳整个ASCII字符集，包括特殊字符吗？
3. Is std::wstring supported by all popular C++ compilers? 所有流行的C ++编译器都支持std::wstring吗？
4. What is exactly a " wide character "? 什么是“ 宽字符 ”？
