I've tried the following settings.
It ignores OTC version of ``Noto Sans CJK'' and ``Source Han Sans''.
It does not ignore other OTC fonts.
Right now, the number of available OTC fonts is very small.
So listing all of the well-known OTC fonts would not be difficult.
In the near future, if the number of available OTC fonts are grown,
this way will become unusable.
Anyway, I'll use this way since there is no other better way.
