I'd keep that line: Llet's have the non-math font as Libertinus Serif, I am not mistaken LaTeX's \usepackage{libertinus} does both things in on package (picking Libertinus as main text font and Libertinus Math as math font). Bare SILE needs more lines here (setting the main text font, loading the math support and setting the math font and its size explicitly) for a similar ouyput.

Erm. So we are no longer testing STIX Two Math? We ought, and the output won't be correct in 0.15.9 but will eventually be fixed. No need to remove the case.


Math mode manners:

\set[parameter=math.font.family,value=STIX Two Math]
\begin[mode=display]{math}
\table[columnalign=right left]{
f(x) &= a\prime + b\dprime + c\trprime \\
f\prime(x) &= x^2 + 1
f(x) &= a^\prime + b^\dprime + c^\trprime \\
f^\prime(x) &= x^2 + 1

Seems correct to me, but for full parity with xelatex, we should also see the short-hand variant.

Ah, my misunderstanding in the previous comment, you split the shorthand version. Can we stick closer to the xelatex version?

If this one (lacking the ^ is removed, why do we keep the preceding line? Reading the original description of the test for all languages, I'd tend to guess it expected proper user input (so with a^\prime etc. for the "long" variant, and a' etc. for the short-hand variant), both following The TeXBook. Do we also want to show the output for an incorrect user input? If so, we need both lines, and to explain the issue...

Shouldn't be this one a ^\prime?

Same remarks as for the STIX example.
