我最近安装了 Minion Pro 软件包https://ctan.org/tex-archive/fonts/minionpro并严格遵循自述文件中的所有说明。到目前为止，一切都呈现正确除了常规字体的 % 符号（参见下面的输出示例），被十字框符号取代。
我尝试过其他字体，奇怪的是，对于粗体和斜体，% 字形的呈现方式与应有的方式一致。
为了保持整洁，请考虑以下代码的简单输出示例（如果表面上不清楚，则此包不需要\usepackage[T1}{fontenc}，即使使用它，pdf 中的结果也完全相同）：
\documentclass[a4paper]{article}
\usepackage{MinionPro}
\begin{document}
Let us see if we can make it 100\%.
\textbf{More boldly, 100\%.}
\textit{Or, emphasised -- 100\%.}
$$\sum_{i=1}^NM^\alpha A^{1-\alpha}$$
\end{document}
得出：
我在 Windows 上使用 TexLive 2019。
我已经检查并确认我用于转换的 .otf 字体文件本身没有损坏 - 它们在 MS Word 中给出了正确的字形。
我特意不使用 XeLaTeX 或其他类似的替代字体渲染，因为 MinionPro 包在细节上更强大并且有自己的数学支持。
有没有可用的修复程序？到目前为止我还没找到，很久以前有人在 Stack Exchange 上提出一个未答复的查询，它涉及了完全相同的问题，但由于不够具体而被关闭。
我正在寻找适当的修复方法，而不仅仅是解决方法。
也许，深入研究根据说明安装在 TeX 树中的包中的文件，看看是否只需简单更改一个（或几个文件）的代码即可解决问题，这可能足以解决问题，但我个人没有专业知识也没有时间自己找到它。
我将非常感激明智且信息丰富的回复，因为我真的很喜欢那种字体。
（我对包装和字体映射以及其他类似事物的工作原理没有深入的了解，因此，我希望能够用简单的英语进行解释，以便对普通用户来说也能“显而易见”，而不仅仅是编码和命令行专家。）
编辑 根据要求，制作了一个通过 pdfLaTeX 运行的小文件（称为 minion-2.tex），该文件仅包含 % 符号，并且仅使用 MinionPro 软件包。我获得了这个强大的日志：

答案1
对于感兴趣的人，解决方案（感谢 Ulrike Fischer，请参阅问题下的评论）如下：
转到 /texmf-local/fonts/enc/dvips/MinionPro（假设整个包安装正确）并base-MinionPro-aa.enc使用记事本等打开。在那里，搜索“百分比”（在 下0xD0），您将看到—
% 0xD0
/emdash /oacute /ocircumflex /ograve /one.fitted /one.oldstyle /one.superior /one.taboldstyle
/onehalf /onequarter /otilde /percent.oldstyle /plusminus /registered /seven.fitted /seven.oldstyle
改为，percent.oldstyle即percent
% 0xD0
/emdash /oacute /ocircumflex /ograve /one.fitted /one.oldstyle /one.superior /one.taboldstyle
/onehalf /onequarter /otilde /percent /plusminus /registered /seven.fitted /seven.oldstyle
并保存文件。由于 .pfb 文件（在文件夹中type1）中的字形名称是“percent”，因此编码文件必须具有相应的信息才能正常工作。
瞧，Minion Pro 现在可以在 pdfLaTeX 中使用，而无需使用会产生警告的解决方法。比较与问题中相同代码的输出：
