-nttF:
When a NTT JTeX Japanese font is replaced by a pTeX (by ASCII Corp.) Japanese font by the -ntt: option, when a new Japanese font is added and defined by \jfont, the added Japanese font name must be taught to the dviout.
The following option "-nttF:" is used here (Property Sheets->[JFont2]).
-nttF:<jfm_file_1>=<added_font_1>;<jfm_file_2>=<added_font_2>;...
Note that in this option, a name not containing the point number (10, 12, etc.) or the resolution (118, 360, etc.) is specified.
