编辑：我误读了 fontforge 的输出。xelatex 是正确的。字形不存在。
我有以下示例文本：
\documentclass[12pt]{article}
\usepackage{fontspec}
\usepackage[english]{babel}
\setmainfont{Times_New_Roman.ttf}[
Path = {/path/to/local/font/files},
BoldFont = Times_New_Roman_Bold.ttf,
ItalicFont = Times_New_Roman_Italic.ttf,
BoldItalicFont = Times_New_Roman_Bold_Italic.ttf
]
\begin{document}
\symbol{9745}
\end{document}
我确实知道我使用的字体包含 U+2611（十进制 9745）的字形，因为我是在 fontforge 中打开它的。
现在，当我使用 xelatex 处理它时，生成的 PDF 中会出现一个缺少的字符占位符，同时日志中出现以下错误：
Missing character: There is no ☑ in font [/path/to/local/font/files/Times_New_Roman]/OT:mapping=tex-text;!
我不知道是否有我错过的神奇选项，但我认为这应该是有效的，而我所做的所有谷歌搜索都让人们认为字符存在于他们的字体中，但实际上并不存在。
我尝试将字符直接粘贴到 tex 中，以及使用上例中看到的 \symbol。
我可以在日志中看到它已成功加载字体。以下是日志中的内容，以防万一它包含有用的信息：

告诉我们字体在插槽 9745 处没有字形，您可以在此处看到一个红色十字。顶部只是一种用可能的视觉表示来标记插槽的方式。
您可以从另一种字体导入字形：
\newfontface{\mysymbols}{FreeSerif}
\newcommand{\ballotboxwithcheck}{{\mysymbols\symbol{9745}}}
