[features,parsers] implement font fallbacks
Building on the combination mechanism, this allows defining fallback fonts of which all glyphs are pulled that aren’t currently part of the base font. Example: \input luaotfload.sty \font \lm = file:lmroman10-regular.otf:mode=base \font \cmu = file:cmunrm.otf:mode=base \font \lmu = "combo: 1->\fontid\lm; 2->\fontid\cmu,fallback" \lmu Eh bien, mon prince. Gênes et Lueques ne sont plus que des apanages, des поместья, de la famille Buonaparte. \bye This allows setting Latin Modern text that contains Cyrillic letters. Note that -- as with the other combinations -- only glyphs are considered, no other properties of the fallback font. So besides the occasional letter in a different script this functionality is probably useless.
