Hi Juan,

Yep, so in my config’s implementation I have an alist of fontset names and
individual fonts. For something part of org-mode itself, we’d probably want to
add a format level to this, something like:

┌────
│ ((fontset-name .
│   ((serif .
│     ((pdflatex . "\\usepackage{myserif}")
│      (lualatex . "etc.")
│      (html . "and so on")))
│    (sans ...) ... ))
│ (another-fontset ...) ...)
└────

Actually, now that I think of it maybe it would be better to seperate out the
fontsets and fots, e.g.

┌────
│ ;; Fonts
│ ((myfonta . ((pdflatex . "etc.") (lualatex ...) (html ...) ...))
│  (myfontb ...)
│  ...)
│ ;; Fontsets
│ ((myfontset .
│   ((sans . myfonta)
│    (serif . myfontb)
│    (mono . myfontc)
│    ...))
│  ...)
└────

Sure. There’s another bit of functionality in my config which I think is worth
noting, you can add a -sans/-serif/-mono suffix to the fontset name to override
the default body text font.

All the best,
