Can we somehow use NFSS? Can we add support for harfbuzz to fontspec?

I don’t know much a lot NFSS or fontspec. But my impression was that shaping etc. happens in luaotfload. luaotfload in turn uses a bundled copy of ConTeXt’s fontloader. What would be nice is to have harfbuzz as an option in luaotfload, in addition to ConTeXt's fontloader.

Yes, inclusion in luatfload would be nice, but it probably depends on inclusion of libraries in TeX Live. With some simple font selection scheme we can test real LaTeX documents right now.

@josephwright and I could probably look at latex/NFSS but in my case I'd probably need to build on cygwin as that's the texlive platform I usually use. Will look later...

I've renamed and modified files eu2enc.def and eu2lmr.fd, provided by fontspec, as EU3 font encoding and it seems to work nicely. Can \DeclareFontShape comand be used without .fd files?

I am quite interested in building on Windows, I've tried it, but wasn't successful.

I've pushed the team already to say we shouldn't have more than one Unicode encoding (it's a font loading variation, not an encoding one). A third 'encoding' makes this more urgent: I'll push the rest of the team again to address this properly. (It's quite doable, just needs a decision.)

At this stage just whatever is easiest although there is an outstanding issue on fontspec to use the same encoding (called say UC for unicode) with luatex and xetex so same could be used here, the different encodings are not really different encodings just used as a hook for minor differences in font loading syntax, but having different encodings complicates other things.

Yes, fontspec only needs fd files normally for fonts like latin modern that exist in a range of design sizes. In the normal system font case where just using one scaled font, it does not need them.

Ah, fine, I thought it would be better to use own encoding, but EU2 works as well.

Great, it makes things quite easy, I think :)

I've added simple font selection: f7a2cc07f55197974eb629523dcd1a3adab2b306
