marvosym 符号不起作用

Question

我想使用一些符号，marvosym但它们似乎在我的发行版中不起作用。

\documentclass{article}
\usepackage[english]{babel}
\usepackage{marvosym}

\begin{document}

$\Bat$
$\Bicycle$
$\Coffeecup$ 
$\Frowny$ 
$\Heart$
$\Industry$ 
$\Football$
$\Mobilefone$
$\Smiley$
$\Womanface$
$\Gentsroom$
$\Ladiesroom$
$\Taurus$
$\Sagittarius$
$\WomanFace$
$\ManFace$
$\Yingyang$
\end{document} 

我得到如下 PDF 输出：

我正在使用 TeXstudio 2.6.6。我的 MiKTeX 包管理器有一个按需加载设置，所以也许我缺少其他字体的包？目前，我对如何解决这些缺失字符错误一无所知（我假设它们会随包一起安装）。

有什么想法可以解决这个问题吗？

（我希望问题不要太过局部化，但我确实有一个非常标准的设置。）

Answer 1

符号不能在纯数学模式下使用。删除符号$...$周围的 或将\text{}符号宏名称 ( \usepackage{amsmath}) 括起来即可。

\documentclass{article}
\usepackage[english]{babel}
\usepackage{marvosym}

\begin{document}

\Bat
\Bicycle
\Coffeecup 
\Frowny 
\Heart
\Industry 
\Football
\Mobilefone
\Smiley
\Womanface
\Gentsroom
\Ladiesroom
\Taurus
\Sagittarius
\WomanFace
\ManFace
\Yingyang
\end{document} 

Answer 2

的符号命令marvosym是文本模式命令，如 Christian Hupfer 的回答。

由于marvosym的符号宏是基于较低级别的宏定义的\mvchr，因此可以轻松修补这些宏以使其在数学模式下工作，例如：

\documentclass{article}
\usepackage[english]{babel}
\usepackage{marvosym}

\usepackage{amstext}
\usepackage{etoolbox}
\pretocmd\mvchr{\text}{}{\errmessage{Patching \noexpand\mvchr failed}}
\pretocmd\textmvs{\text}{}{\errmessage{Patching \noexpand\textmvs failed}}

\begin{document}

$\Bat$
$\Bicycle$
$\Coffeecup$
$\Frowny$
$\Heart$
$\Industry$
$\Football$
$\Mobilefone$
$\Smiley$
$\Womanface$
$\Gentsroom$
$\Ladiesroom$
$\Taurus$
$\Sagittarius$
$\WomanFace$
$\ManFace$
$\Yingyang$
\end{document}
