[Q] TFM files headers

[Hironobu Yamashita]

Hi Tom,

Some of TFM files you've listed are JFM (Japanese pTeX font metric),
though they have .tfm not .jfm.
All of the below are in JFM format.
We Japanese use those files on a daily basis ;-)

You can check whether a .tfm is an ordinary TFM or pTeX JFM by

$ chkdvifont /path/to/something.tfm
