copied!<p>There's no way to write the string literal directly in UTF-8 with the current versions of VC++. A future version should have <a href="http://en.wikipedia.org/wiki/C++11#New_string_literals" rel="nofollow">UTF-8 string literals</a>.</p> <p>I tried pasting non-ASCII text directly into a string literal in a source file and saved the file as UTF-8. Looking at the source file in a hex editor confirmed that it's saved as UTF-8, but that still doesn't do what you want. At compile time, those bytes are either mapped to a character in the current code page or you get a warning.</p> <p>So the most portable way to create a string literal right now is to explicitly write the octets as you've been doing.</p> <p>If you want to do a run-time conversion, there are a couple options.</p> <ol> <li>The Windows API has <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/dd374130%28v=vs.85%29.aspx" rel="nofollow">WideCharToMultiByte</a>, which can take a text as UTF-16 and convert it to multibyte encodings like UTF-8.</li> <li>If you're using a new enough version of the compiler and the C++ runtime, you can use <a href="http://en.cppreference.com/w/cpp/locale/codecvt" rel="nofollow"><code>std::codecvt</code></a> to transform your wide character string into UTF-8.</li> </ol> <p>You could use one of these techniques to write a little utility that does the conversion and outputs them as the explicit octets you would need for a string literal. You could then copy and paste the output into your source code.</p>
