Installing APM Database localization problem

Idea created by T-KURODA on Aug 9, 2016

    Installing APM Database for Windows with the language as Korean or Chinese or Japanese,
    install_db.log always contains garbled characters (they are originally multi byte characters).
    I had contacted the support to fix this. But they told me "It won't be fixed because the impact is very small." <- under discussion.
    So, I'm posting here.
    Incidentally, during installing, the characters are still not garbled.
    In the timing of finishing installing, they will be garbled. That's odd.
    I want you to fix it.
