“在 Beamer 中使用 unicode-math 时缺少项目符号”的替代方案

“在 Beamer 中使用 unicode-math 时缺少项目符号”的替代方案

我知道，已经有了在 beamer 中使用 unicode-math 时缺少项目符号但唯一且被接受的答案“不要使用 unicode-math“不是我所需要的，因为我也想改变我的数学字体，而且根据我的理解，这需要unicode-math。

所以我的问题是至少两种可能的答案

  1. 如何告诉 Beamer 使用不同的机制来列出要点而不关心unicode-math。
  2. 如何在不使用的情况下指定数学字体unicode-math

这是我的设置（我使用 XeLaTeX）

\documentclass[aspectratio=149]{beamer}
\usefonttheme[onlylarge]{structurebold}
\usecolortheme[RGB={150,0,80}]{structure} 
\setbeamertemplate{navigation symbols}{}

这是 gzip 压缩日志文件的 uuencoded 版本（我无法发布文件本身，因为它超出了 SE 帖子中 30,000 个字符的限制）。

编辑注：删除了 uuencoded gzip 日志，并用相关片段替换。完整日志可在编辑历史中找到。缺失的字符U+25B6是一个‘黑色右指三角形’。

答案1

A简单的解决方法是

\setbeamertemplate{items}[square]

在我看来，问题在于旧版本的 Cambria Math，其中不包含黑色右指向三角形的提示。

我修改过的例子

\documentclass[aspectratio=149]{beamer}
\setbeamertemplate{items}[square]
\usefonttheme[onlylarge]{structurebold}
\usecolortheme[RGB={150,0,80}]{structure} 
\setbeamertemplate{navigation symbols}{}
%%%%%% FONTS
\usepackage{fontspec}
\usepackage{unicode-math}
\setmainfont[Mapping=tex-text,Numbers=Lining]{Cambria}
\setsansfont[Mapping=tex-text,Numbers=Lining]{Calibri}
\setmonofont[Scale=0.95]{Consolas}
\setmathfont{Cambria Math}
%%%%%% /FONTS
