在我的 TeX Live 2021 发行版最近更新后，我在旧文档中收到以下类型的警告消息：
Font shape `TU/lmss/m/sc' in size <10> not available
(Font) Font shape `TU/lmr/m/sc' tried instead.
这导致文档的标题（在sffamily和 中scshape）与之前的结果看起来不同。有什么方法可以解决这个问题吗？
以下是 MWE：
%! TEX program = xelatex
\documentclass{article}
\usepackage{newpxtext}
\begin{document}
\textsf{\textsc{Some Text}}
\end{document}

答案1
使用以前的版本时newpxtext您没有获得 OpenType 字体：
<[email protected](TFM:ec-qhvr-sc)(Encoding:q-ec-sc.enc)
pdf_font>> Simple font "qhvr.pfb" enc_id=<q-ec-sc.enc,3> opened at font_id=<ec-qhvr-sc,0>.

>](qhvr.pfb[Type1])(zplr.pfb[Type1])
在新版本中，fontspec使用 TeX Gyre PagellaX 作为主要字体，但没有选择无衬线字体。因此，您得到的是 Latin Modern Sans，它没有小写无衬线字体。
您需要声明一种无衬线字体，例如 TeX Gyre Heros。
\documentclass{article}
\usepackage{newpxtext}
\setsansfont{texgyreheros}[
Scale=MatchLowercase,
UprightFont=*-regular,
BoldFont=*-bold,
ItalicFont=*-italic,
BoldItalicFont=*-bolditalic,
]
