POHow to set file encoding format to UTF8 in C++
text
Body
copied!<p>A requirement for my software is that the encoding of a file which contains exported data shall be UTF8. But when I write the data to the file the encoding is always ANSI. (I use Notepad++ to check this.)</p> <p>What I'm currently doing is trying to convert the file manually by reading it, converting it to UTF8 and writing the text to a new file.</p> <p><code>line</code> is a <code>std::string</code><br> <code>inputFile</code> is an <code>std::ifstream</code><br> <code>pOutputFile</code> is a <code>FILE*</code> </p> <pre><code>// ... if( inputFile.is_open() ) { while( inputFile.good() ) { getline(inputFile,line); //1 DWORD dwCount = MultiByteToWideChar( CP_ACP, 0, line.c_str(), -1, NULL, 0 ); wchar_t *pwcharText; pwcharText = new wchar_t[ dwCount]; //2 MultiByteToWideChar( CP_ACP, 0, line.c_str(), -1, pwcharText, dwCount ); //3 dwCount = WideCharToMultiByte( CP_UTF8, 0, pwcharText, -1, NULL, 0, NULL, NULL ); char *pText; pText = new char[ dwCount ]; //4 WideCharToMultiByte( CP_UTF8, 0, pwcharText, -1, pText, dwCount, NULL, NULL ); fprintf(pOutputFile,pText); fprintf(pOutputFile,"\n"); delete[] pwcharText; delete[] pText; } } // ... </code></pre> <p>Unfortunately the encoding is still ANSI. I searched a while for a solution but I always encounter the solution via MultiByteToWideChar and WideCharToMultiByte. However, this doesn't seem to work. What am I missing here?</p> <p>I also looked here on SO for a solution but most UTF8 questions deal with C# and php stuff.</p>
