subsetting NotoSansCJK (otf)
Has anyone ever succeeded in subsetting NotoSansCJK series (otf) with fontmin?
I have tried following processes but have never succeeded...

- plan A
  - step1. once convert otf => ttf by Fontmin.otf2ttf
  - step2. generate subset fonts from the ttf file by Fontmin.glyph
- plan B
  - step1. once convert otf => woff => ttf by [woff converter](https://opentype.jp/woffconv.htm)
  - step2. generate subset fonts from the ttf file by Fontmin.glyph

AFAIK, there is only way to generate subset fonts of NotoSansCJK (jp) is using [subset font maker](https://opentype.jp/subsetfontmk.htm) which is a free software in Japan. But, I don't want to use GUI software and I want to generate them dynamically by a program written in Node.js or something...
