Calling string() on environment variables with empty values fails on Windows #554
Description
When I have environment variables with no values (somehow I have two on my system - COMPLUS_InstallRoot and COMPLUS_Version), when I iterate over values of boost::process::environment::current() and try to call string() on the empty value, it fails.
boost::unordered_map<std::string, std::string> currentProcessEnvironment;
for (const auto& env : boost::process::environment::current())
{
currentProcessEnvironment[env.key().string()] = env.value().string(); // fails if env.value().empty()
}
Fix for this should be simple, all needed should be just to apply this for size_as_utf8 and convert_to_utf8: f372a9a

I am too busy with other things. I can create PR later but I don't know when.

@klemens-morgenstern: Any update on this? Boost 1.92.0 has been released approx. a month ago, so now the pull request fixing this issue (#560) could be reviewed.
