\sigma prints Greek varsigma rather than Greek sigma in sf types

[kia999]

I noticed that \sigma prints something wrong in sf. See attached example. I tested it with XeLaTeX from MikTeX.

\documentclass{article} \usepackage{unicode-math} \setmathfont[Color=000066,Scale=MatchLowercase]{STIX Two Math} %\setmathfont[Color=000066,Scale=MatchLowercase]{STIX} \usepackage{amsmath} \renewcommand{\vec}[1]{\symbf{#1}}

\begin{document} \begin{gather} %\label{} (): {\sigma}{\pi}{P}{\eta} \ (\text{mathbfsfit}): \mathbfsfit{\sigma}\mathbfsfit{\pi}\mathbfsfit{P}\mathbfsfit{\eta} \ (\text{symbfsfit}): \symbfsfit{\sigma}\symbfsfit{\pi}\symbfsfit{P}\symbfsfit{\eta} \ (\text{mathbfsf}): \mathbfsf{\sigma}\mathbfsf{\pi}\mathbfsf{P}\mathbfsf{\eta} \ (\text{mathbf}): \mathbf{\sigma}\mathbf{\pi}\mathbf{P}\mathbf{\eta} \ (\text{symbf}): \symbf{\sigma}\symbf{\pi}\symbf{P}\symbf{\eta} \end{gather} \end{document}

Thanks. Will check encoding of the two sigmas in the math sans serif sets for the next release.

This appears to be limited to XeTeX; the math alphabets come out as expected in luaTeX. It will require further research.
