ref. https://h20y6m.github.io/posts/2023-12-02-texadvent2023/

使い方

1. zrotfdump.pl を入手
2. zrotfdump.pl を使用して ipamjm.ttf からグリフ一覧を取得

$ perl zrotfdump.pl name ipamjm.ttf > ipamjm-name.txt

3. この ipamjm.py を使って ZVP ファイルを作成

$ python3 ipamjm.py

4. ZVP から VF/JFM を作成

$ jfmutil zvp2vf ipamjmm--h
$ jfmutil zvp2vf ipamjmm--v

メモ

Windows の TeX Live に同梱されている perl を使うときは zrotfdump.pl の 41 行目をコメントアウトする。
