如何在Windows中使用C ++将UTF-8编码的字符串写入文件 [英] How do I write a UTF-8 encoded string to a file in windows, in C++

问题描述

我有一个字符串，可能有或可能没有unicode字符，我试图将其写入Windows上的文件。下面我已经张贴了一个样本位的代码，我的问题是，当我打开并读取值回退窗口，他们都被解释为UTF-16字符。

I have a string that may or may not have unicode characters in it, I am trying to write that to a file on windows. Below I have posted a sample bit of code, my problem is that when I fopen and read the values back out windows, they are all being interpreted as UTF-16 characters.

char* x = "Fool";
FILE* outFile = fopen( "Serialize.pef", "w+,ccs=UTF-8");
fwrite(x,strlen(x),1,outFile);
fclose(outFile);

char buffer[12];
buffer[11]=NULL;
outFile = fopen( "Serialize.pef", "r,ccs=UTF-8");
fread(buffer,1,12,outFile);
fclose(outFile);

如果我在wordpad等中打开文件，字符也被解释为UTF-16。做错了？

The characters are also interpreted as UTF-16 if I open the file in wordpad etc. What am I doing wrong?

推荐答案

是的，当您指定文本文件应以UTF-8编码时，CRT隐含地假定你将把Unicode文本写入文件。没有这样做没有意义，你不需要UTF-8。这将正常工作：

Yes, when you specify that the text file should be encoded in UTF-8, the CRT implicitly assumes that you'll be writing Unicode text to the file. Not doing so doesn't make sense, you wouldn't need UTF-8. This will work proper:

wchar_t* x = L"Fool";
FILE* outFile = fopen( "Serialize.txt", "w+,ccs=UTF-8");
fwrite(x, wcslen(x) * sizeof(wchar_t), 1, outFile);
fclose(outFile);

或：

char* x = "Fool";
FILE* outFile = fopen( "Serialize.txt", "w+,ccs=UTF-8");
fwprintf(outFile, L"%hs", x);
fclose(outFile);
