Dear list,
I have been using the Lucida fonts for long time with LaTeX, either the
Type 1 version through the `lucimatx` package or the OpenType variants
with `unicode-math`. In `unicode-math` there is a straightforward way
to select stylistic sets, e.g. alternative calligraphic glyphs.
By default the `lucidaot` typescript switches off the alternative math
italics, but I found a way to reenable them (basically just undoing what
the typescript does).
\setupbodyfont[lucidaot]
% get alternative math italics
\setupmathrendering[lucidaot][it=]
\starttext
$\mathcal{C} = f(x)$
\stoptext
I only found this by chance; \setupmathrendering is not documented. Is
there a more intuitive way to select the alternative math italics?
Also, is there an easy way to access all the other features defined in
`lucida-opentype-math.lfg`? This is the list:
alternates = {
italic = { feature = 'ss01', value = 1, comment = "Mathematical
Alternative Lowercase Italic" },
arrow = { feature = 'ss02', value = 1, comment = "Mathematical
Alternative Smaller Arrows" },
operator = { feature = 'ss03', value = 1, comment = "Mathematical
Alternative Smaller Operators" },
calligraphic = { feature = 'ss04', value = 1, comment = "Mathematical
Alternative Calligraphic Characters" },
zero = { feature = 'ss05', value = 1, comment = "Mathematical
Alternative Zero" },
partial = { feature = 'ss20', value = 1, comment = "Mathematical
Alternative Upright Partial Differential" },
},
I extended the mechanism a bit so in the next beta you can do
combinations and a global setup:
\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
