Unicode 将GetPrivateProfileStringW与UTF-8编码文件一起使用？

unicode utf-8 mfc

Unicode 将GetPrivateProfileStringW与UTF-8编码文件一起使用？,unicode,utf-8,mfc,ini,Unicode,Utf 8,Mfc,Ini,到目前为止，我的INI文本文件已经进行了Unicode编码，我一直在这样做来读取它： ::GetPrivateProfileStringW( strUpdateSection, strTalkKey, _T(""), strTalk.GetBuffer( _MAX_PATH ), _MAX_PATH, m_

到目前为止，我的INI文本文件已经进行了Unicode编码，我一直在这样做来读取它：

::GetPrivateProfileStringW(
                strUpdateSection,
                strTalkKey,
                _T(""),
                strTalk.GetBuffer( _MAX_PATH ),
                _MAX_PATH,
                m_strPathINI );
strTalk.ReleaseBuffer();
该文件首先从internet下载，然后访问。但是我发现对于阿拉伯语来说，文本文件已经损坏。除非我将编码更改为UTF-8。当我这么做的时候，它会正确下载。但是它不能正确地从INI读取数据

那个么INI文件必须是Unicode编码的吗？或者在函数调用中使用UTF-8也可以吗

我想是时候把程序的这一部分转换成UTF-8编码的XML文件了！干得好

但我想先问个问题

我应该澄清一下，文本文件最初是使用记事本保存为UTF-8的

函数将处理UTF-8编码的INI文件，但仅当该文件上有UTF-8 BOM时，否则该函数要求该文件编码为UTF-16。

函数将读取没有BOM的UTF-8编码文件（但不会处理不使用操作系统当前Ansi字符集的Unicode文件名），但它不知道该文件正在使用UTF-8，因此它只会按原样返回UTF-8数据，您必须手动将其转换为UTF-16。“该文件为Unicode。”-Unicode是一个标准。这不有趣。有趣的是使用的编码。我不知道Unicode字符编码，它不能表示阿拉伯文本。您是否单步通过代码找到字符串不显示预期内容的最早点？确保正确解释字符串内容ts在调试器中，在“监视”窗口中使用适当的。没有任何迹象表明文件下载点已损坏。您正在将其加载到类型为

中。调试器的文本可视化工具将假定这是ANSI编码（不是UTF-8或UTF-16）。我建议使用带有适当格式说明符的“监视”窗口。这是确保数据按您希望的方式解释的唯一方法。您的屏幕截图显示了将解释留给调试器可视化工具的结果（调试器可视化工具出错）.输入

作为监视表达式应将内容解释为UTF-8编码字符串。
