安装 TeX Live 2022 后，我pdflatex（两次）编辑了https://github.com/latex3/hyperref/blob/main/test/testbmgl.tex。生成的书签与 TeX Live 2015 创建的书签有很大不同：
是测试失败了还是我的安装失败了（以及我该如何修复它）？
日志文件是这样的：

那么，我需要“字体编码 PD1 的 UTF-8 映射文件”吗？我在哪里可以得到它或者如何创建一个？
答案1
编辑 2023
babel-greek 维护者现在已完成对 greek 的支持。如果您使用任何激活 greek 的选项（例如，将 greek 与 babel 一起使用，或者如果您加载 LGR 字体编码），则通常会加载它。
您可以加载 psdextra 集，它定义了一小组希腊命令名称：
