当我尝试在 moderncv 中启用 fontawesome 图标时，日志中出现此错误pdflatex：
! LaTeX Error: Encoding scheme `TU' unknown.
一个简单的例子：
\documentclass[11pt,a4paper,sans]{moderncv}
\moderncvstyle{casual}
\moderncvcolor{blue}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage{babel}
\name{John}{Doe}

\social[googlescholar]{ADFIE89AD}
\moderncvicons{awesome}
\renewcommand*{\bibliographyitemlabel}{[\arabic{enumiv}]}
\begin{document}
\makecvtitle
foo
\end{document}
在fontawesomebrands.fd和fontawesomepro.fd 中有很多对的引用TU，所以它似乎是某种核心元素。但是没有来自的任何提示pdflatex，也没有在谷歌搜索中找到任何信息，我无法找出缺少什么或配置错误的地方。
更新：日志文件中的摘录看起来与 fontawesome 相关（因为无法发布实际的日志文件附件）：

答案1
未知消息TU表明您正在尝试在 pdfLaTeX 文档中使用仅适用于 LuaLaTeX 和 XeLaTeX 的字体包。
导致该问题的字体是当选择时academicons会自动加载moderncv至版本 2.1.0 的字体。\moderncvicons{awesome}
在moderncv2.2.0 版本（于 2021-07-28 发布）中，\moderncvicons{awesome}已更改为不再自动加载academicons，因此与 pdfLaTeX 兼容。
因此，为了解决这个问题，你需要安装一个更新的moderncv版本。最新版本 (v2.3.1) 仍然包含在 TeX Live 2021 中，因此您可以通过更新到 TeX Live 2023 或安装现有 TeX Live 2021 的软件包更新来执行此操作。尝试更新现有安装时，请记住，自 TeX Live 2022 发布以来，默认镜像不再包含 TeX Live 2021 的软件包，因此要更新 TeX Live 2021，您必须按照说明进行操作用于更新历史分布。这是假设您手动安装了 TeX Live。如果您从某个分发包中获取了它，则需要按照常规步骤更新您的包。
