Dear list, I noticed that LuaTeX has problems with certain unicode characters in LyX 2.4.1. So far, the list contains U+0361, U+034F, U+2E3A, U+2E3B. "LaTeX Error: Unicode character [...} not set up for use with LaTeX." As XeTeX is greyed out now, I cannot test if it has a problem as well. Is it a bug? Kind regards, Bernd
