Just to say that I seem to have resolved this (& properly I hope). I read these two pages: https://www.contextgarden.net/Faking_characters https://source.contextgarden.net/tex/context/base/mkiv/enco-ini.mkiv?search=... and have included the following with my setups: % Additional Characters \definecharacter llowmacron {\buildtextmacron l} \definecharacter Llowmacron {\buildtextmacron L} \definecharacter nlowmacron {\buildtextmacron n} \definecharacter Nlowmacron {\buildtextmacron N} \definecharacter rlowmacron {\buildtextmacron r} \definecharacter Rlowmacron {\buildtextmacron R} \define\lLM{\llowmacron} \define\LLM{\Llowmacron} \define\nLM{\nlowmacron} \define\NLM{\Nlowmacron} \define\rLM{\rlowmacron} \define\RLM{\Rlowmacron} This seems to do it, although if there is a better way please feel free to say.

Still, I would prefer to still with LM. I'm wondering if there is a way in Context to set up these characters on the fly, say with something along the lines of "newunicodechar"? \newunicodechar{<char>}{<code>} \newunicodechar{ā}{\accent"0304 a} newunicodechar -- Definitions of the meaning of Unicode characters https://ctan.org/pkg/newunicodechar?lang=en Best, Richard
