[NTG-context] Using Farad with \unit messes up feet, µ not recognised as prefix

Hi! I struggle using the unit Farad (unit of capacitance): \starttext %% prints 10 10 ft \unit{10 F} \unit{20 ft} \registerunit [F=Farad] \setupunittext [Farad=F] %% prints 10 F 20 F⋅t \unit{10 F} \unit{20 ft} \stoptext When registering Farad as new unit it messes up feet. This looks like a bug to me, since “20 ft” does not contain a capital “F” and units are case-sensitive. How to use Farad correctly without messing up other units? 2nd issue: The prefix “µ” is not recognised: \starttext %% prints 10 nm 20 30 µm \unit{10 nm} \unit{20 µm} \unit{30 um} \stoptext I would expect “20 µm” to produce the correct result. Can we make “µm” also produce the same result as “um”? Marco LMTX 2023.09.04 19:15
