Request for ⊻ (U+22BB) in Libertinus Math Regular

[kylebgorman]

Describe the bug

U+22BB is apparently not supported by the LaTeX libertinus package, and I don't see it in list of supported symbols; this symbol, usually denoted \veebar in LaTeX math, is used for (logical) exclusive OR.

Steps to reproduce

Here is a minimal LaTeX example. Contents of minimal.tex:

\documentclass{article}
\usepackage{libertinus}
\begin{document}
Logical exclusive OR is denoted by $\veebar$.
\end{document}

To compile, run xelatex minimal.tex. This produces a warning:

Missing character: There is no ⊻ (U+22BB) in font [LibertinusMath-Regular.otf]/
OT:script=math;language=dflt;;!

And the resulting PDF has tofu where the veebar should be; see below.

Expected vs. actual behavior

I expected this common mathematical symbol to be present in the font; it's not.

Additional context

I am using XeTeX 3.141592653-2.6-0.999995 (TeX Live 2023), though I doubt it matters much.
