要将std::wstring 转换为 std::string,我们需要考虑编码方式,因为 std::wstring 使用wchar_t 类型来存储宽字符,而 std::string 使用char 类型来存储单字节字符。以下是一种常用的转换方法,使用标准库函数来实现: 1. 理解 std::wstring 和std::string 的区别 std::wstring 用于存储宽字符字符串,通常用于国际化...

I think you don't need to convert anything: if inPath and outPath are already Unicode (UTF-16), you can just use std::wstring and you're done: std::wstring appParams = L" tracks " + inPath + L" 1: " + outPath; Just note the "L" decoration used for string literals. If you...
Class template std::wstring_convert performs conversions between byte string std::string and wide string std::basic_string<Elem>, using an individual code conversion facet Codecvt. std::wstring_convert assumes ownership of the conversion facet, and cannot use a facet managed by a locale. The ...
