使用boost::log::init_from_settings时如何调用sink->imbue？

#include <boost/log/utility/setup/from_settings.hpp>
#include <boost/log/sinks/sync_frontend.hpp>
#include <boost/log/sinks/text_ostream_backend.hpp>
#include <boost/log/sinks.hpp>
#include <boost/log/core.hpp>
#include <boost/log/expressions.hpp>
#include <boost/log/trivial.hpp>

int main()
{
    // 创建一个settings对象
    boost::log::settings logSettings;

    // 添加sink到settings对象中，并保存返回的shared_ptr
    boost::shared_ptr<boost::log::sinks::text_ostream_backend> backend =
        boost::make_shared<boost::log::sinks::text_ostream_backend>();
    boost::shared_ptr<boost::log::sinks::synchronous_sink<boost::log::sinks::text_ostream_backend>> sink =
        boost::make_shared<boost::log::sinks::synchronous_sink<boost::log::sinks::text_ostream_backend>>(backend);
    logSettings["Sinks"]["Sink1"] = boost::log::settings::section_type();
    logSettings["Sinks"]["Sink1"]["Type"] = "Text";
    logSettings["Sinks"]["Sink1"]["Destination"] = "Console";
    logSettings["Sinks"]["Sink1"]["Text"]["Format"] = "%Message%";

    // 调用init_from_settings函数，将日志配置应用到当前的日志系统中
    boost::log::init_from_settings(logSettings);

    // 调用sink->imbue函数，将sink与特定的locale关联起来
    sink->imbue(std::locale());

    // 使用日志系统
    BOOST_LOG_TRIVIAL(info) << "Hello, World!";

    return 0;
}
