I get a different result for mkiv and lmtx for the following input:

\starttext Even now, a six footer is two standard deviations from the mean. Remember, 5\prime{}7\prime\prime{} is 50th percentile today for a 15 year old. \stoptext

With mkiv, the prime marks for inches and feet are where I expect them; in lmtx, they are placed almost to the baseline.

Wrong lmtx, or user error?

% you can add this to cont-new.mkxl \immutable\Umathchardef\minute\zerocount\zerocount\privatecharactercode{prime 0x2032 1} \immutable\Umathchardef\second\zerocount\zerocount\privatecharactercode{prime 0x2033 1} \starttext Even now, a six footer is two standard deviations from the mean. Remember, 5\minute7\second\ is 50\high{th} percentile today for a 15 year old. \stoptext I need to discuss this with Mikael as it assumes that all math fonts are set up that way). In lmtx (luametatex) primes are native features and assume dimensions that we can work with (primes and minutes are a typical example of messed up math unicode).
