I see...

So let's forget Unifont and "Sarasa Mono" for the time being.

By adding some custom configuration of fontconfig, "Noto Sans Mono
CJK SC" can be made an alias of "Sarasa Mono", "Unifont", or whatever
alternative font one wants to try.

An alternative *true* monospace font is just a nice-to-have for
those who concern PDF of Korean translation, and as I have said
earlier, it has another major issue of white spaces being ignored
by xeCJK.

I'll do a v2 along this line.

        Thanks, Akira
