文件在击中宽字符后截断 [英] File truncates after hitting a wide character

问题描述

在尝试向文件中写入某些宽字符时，所有输出到该文件的输出将在这些字符之后停止。我不知道发生了什么。

While trying to write some wide characters to a file, all output to the file stops after those characters. I don't know what's going on.

wofstream file("c:\\test.txt");

file << L"seen" << L"您好" << "unseen";

推荐答案

源代码中的非ASCII字符实现定义方式。使用十六进制序列或更新的（后c99或C ++ 11）unicode字符文字，并使用其UTF-8/16/32代码点表示。

Non-ASCII characters in source code are parsed in an implementation defined way. Use either hex sequences or the newer (post-c99 or C++11) unicode character literals and use their UTF-8/16/32 codepoint representations.

实现定义的行为，所以除非你绝对确定你的编译器是你期望的，不要这样做。

This is implementation defined behavior, so unless you are absolutely sure you compiler does what you expect, don't do this.
