\setupmathematics with stylealternative not working
Hi, It seems that, with the latest beta, the \setupmathematics with stylealternative is not working. I tried \setupbodyfont[lucidaot] \setupmathematics[stylealternative={calligraphic}] \starttext \startTEXpage[offset=3bp] $\mathcal A$ \stopTEXpage \stoptext and got the attached output lcm.png. This is not the curly A I would expect. The one I expect is the one that can be seen on top of page 9 in https://tug.org/store/lucida/lucida-amsmath.pdf. I also noticed that the example file that I have seen earlier on this list, pasted below, does not seem to change anything. Has anything changed? /Mikael % second example \setupbodyfont[lucidaot] \starttext $x ^{i \leftarrow 0 = ∅} _{\setmathfontalternate{arrow} \setmathfontalternate{dotless} \setmathfontalternate{zero} i \leftarrow 0 = ∅} $ $x ^{i \leftarrow 0 = ∅} _{\setmathfontalternate{arrow,dotless,zero} i \leftarrow 0 = ∅} $ \setupmathematics[stylealternative={arrow,dotless,zero}] $x ^{i \leftarrow 0 = ∅} _{i \leftarrow 0 = ∅} $ \stoptext
I can confirm. My workaround which predates the stylealternative mechanism also stopped working, so there must be an issue on the level of font feature selection. \definefontfeature [math-text] [math-text] [ss04=yes] \definefontfeature [math-script] [math-script] [ss04=yes] \definefontfeature [math-scriptscript] [math-scriptscript] [ss04=yes] \setupbodyfont[lucidaot] \starttext \startTEXpage[offset=3bp] $\mathcal A$ \stopTEXpage \stoptext On 2/22/19 8:35 PM, Mikael P.

I just realized that there is still some problem with the stylealternative: With the document %% TEST 1 \setupbodyfont[lucidaot] \setupmathematics[ stylealternative={calligraphic}, ] \starttext $x+\mathcal A$ \stoptext %%% I get both the calligraphic AND the italic keys enabled, even though the italic key should not be set. However, with the test file %%% TEST 2 \setupbodyfont[lucidaot] \setupmathematics[ stylealternative={italic}, ] \starttext $x+\mathcal A$ \stoptext %%% I do not get any of them enabled. In particular the italic key is not enabled, which I assume it should be. /Mikael
