Hi all, Currently fonts with names are longer than 255 characters are ignored and the font fails to load without an explanation. See https://github.com/lualatex/luaotfload/issues/424 for background. The code suggests this is a limitation of the DVI format (the relevant check was add back in 2009 according to repository history), but it shouldn’t affect PDF mode. The attached patch restricts the check to DVI mode and adds an error message. Alternatively the font name can be just truncated in DVI mode (which what happens if the check is removed, but the extra characters are removed from the start of the name, no idea why) an just issue a warning, or use the file name for DVI format since the rest of the spec is irrelevant to DVI files (but this can be debatable, I don’t know if there are any DVI drivers that can parse LuaTeX font names and load the fonts).
