(since C++11) (deprecated in C++17) std::codecvt_utf8是std::codecvt方面,它封装Utf-8编码字节字符串与UC 2或UC 4字符串%28之间的转换,具体取决于Elem29%。这个编解码面可以用来读取和写入UTF-8文件,包括文本和二进制文件. 模板参数 Elem - either char16_t, char32_t
(since C++11) (deprecated in C++17) std::codecvt_utf8_utf16是std::codecvt方面,它封装了UTF-8编码字节字符串和UTF-16编码字符串之间的转换。如果Elem是一种32位类型,一个UTF-16码单元将存储在每个32位字符的输出序列中. 这是一个N:m转换面,不能与std::basic_filebuf%28,它只允许内部编码和外部编码...

So,if there a working way to Convert from CString to std::string in UNICODE builds? Thanks.This will work in either Unicode or MBCS build: CString str = _T("Testing."); std::string s = CT2A(str); David Wilkinson | Visual C++ MVPTuesday...
