Ah, I think this could be separate issue then? It was a bit buried here :)

I was leaving it open as a reminder to myself about adding a default htf to the dvi program, but ... yeah, agreed. (and thanks again for the support.)

I think we can close this issue, as the spectral font is supported.

Maybe it is possible to add a default HTF table to the tex4ht DVI processor? I've tried to look at the source code if something is here already, but I don't understand it at all.

"nofonts" cannot help, because it disables only insertion of the `<span>` elements. The ligature is still in the DVI file, not separate characters.

great, thanks, installed all those files in tl.

wdyt about the general problem of no htf causing ligatures to be lost? maybe could revert to "nofonts" or something if htf not found? i kind of doubt anything like that is plausible, but wanted to get your reaction ...

Hi Karl,

I've added a new generated literate source for spectral. It was quite easy, because they use Unicode codepoints in glyph names for this font, so there are no missing characters :)

hi michal - It seems there are no htf files for the spectral font family (ctan.org/pkg/spectral). maybe you can run your magic setup and make them?

as a result, the following trivial file outputs o^@line (where ^@ is a zero byte) instead of "offline", with both make4ht try.tex and htlatex try.tex <usual args>. is there some way that the defaults can not result in destroying ligatures? probably not an easy thing to figure out, but figured i could ask the question :).
