And more, almost of all dviware can process DVI files generated by NTT
jTeX when appropriate virtual fonts are available, but they cannot
process DVI files generated by ASCII pTeX even when appropriate fonts
are available. DVI files generated by ASCII pTeX contain extended DVI
opcodes to support vertical writing.
