Firebreath和UTF-16

Question

我正在开发一个国际插件，我遇到了UTF-16字符串问题。我正在尝试使用FB :: FactoryBase :: GetLoggingMethods将日志存储到％APPDATA％。目前它的定义如下：

void getLoggingMethods(FB::Log::LogMethodList& outMethods) {
  try {
    boost::filesystem::path appDataPath = FB::System::getLocalAppDataPath("AppName");
    boost::filesystem::path logDirPath = appDataPath / "Logs";

    if(!exists(logDirPath)) {
        // create the directory
        boost::filesystem::create_directories(logDirPath);
    }

    if (exists(logDirPath) && is_directory(logDirPath)) {
        boost::filesystem::path logPath = logDirPath / "app_name.log";

    outMethods.push_back(std::make_pair(FB::Log::LogMethod_File, logPath.string()));
        }
    } catch(...) { /* safely fail here */ }
}

当用户的用户名中包含UTF-16字符时，会出现此问题。这引发了异常。

但是，outMethods.push_back需要输入std::string。从std::wstring转换为std::string会丢失该UTF-16字符（这会使路径无效。）

有什么想法吗？

编辑：设法通过为其构造函数提供boost :: filesystem :: path LPCWSTR来使其工作。

boost::filesystem::path appDataPath = 
    FB::utf8_to_wstring(FB::System::getLocalAppDataPath("AppName")).c_str();

boost::filesystem::path logDirPath = appDataPath / "Logs";

if(!exists(logDirPath)) {
     // create the directory
     boost::filesystem::create_directories(logDirPath);
}

if (exists(logDirPath) && is_directory(logDirPath)) {
    boost::filesystem::path logPath = logDirPath / "app_name.log";

    outMethods.push_back(
         std::make_pair(
             FB::Log::LogMethod_File, FB::wstring_to_utf8(logPath.wstring())
         )
    );
 }
