希腊语问题

我在 pdflatex 中遇到了希腊语问题。几周前，当我使用包管理器更新 Miktex 时，这个问题首次出现。然后在一次新更新后，这个问题消失了，最后在最后一次更新（2016 年 9 月 7 日）后，这个问题又出现了。

最小工作示例如下：

\documentclass[11pt, a4paper]{article}
\usepackage[pdftex]{graphicx}
\usepackage[english,greek]{babel}
\newcommand{\en}{\selectlanguage{english}}
\newcommand{\gr}{\selectlanguage{greek}}
\usepackage[utf8]{inputenc}
\usepackage{Kerkis}
\usepackage[square,numbers]{natbib}

\title{ ΗΛΕΚΤΡΟΜΑΓΝΗΤΙΣΜΟΣ-ΟΠΤΙΚΗ}
\date{08 Σεπτεμβρίου 2016.}
\author{Ανδρέας Ζούπας}
\begin{document}
\maketitle
 Διάρκεια Εξέτασης \textbf{3.0} ώρες.

\end{document}

在更新之前，我一直使用它，没有任何问题。这是我的日志文件：

为了确保我没有做任何根本性的错误，我决定使用相同的结构，但使用英语。实际示例如下：

\documentclass[11pt, a4paper]{article}
\usepackage[pdftex]{graphicx}
\usepackage[english,greek]{babel}
\newcommand{\en}{\selectlanguage{english}}
\newcommand{\gr}{\selectlanguage{greek}}    
\usepackage[utf8]{inputenc}   
\usepackage{Kerkis}    
\usepackage[square,numbers]{natbib}

\title{\en ELECTROMAGNETISM-OPTICS}    
\date{\en 08 September 2016.}    
\author{\en Andreas Zoupas}
\begin{document}

\maketitle

\en
Exam Duration \textbf{3.0} hours.

\end{document}

但是，这个运行起来没有任何问题。

我按照建议做了修改，并用 shareLateX 运行代码，它确实运行正常。我认为这是 MiKTeX 包 babel-greek 的问题，但我不知道如何修复它。

答案1

我想我找到了问题的根源。在 Winedt 10 中，有 ContribManager，它允许用户安装宏或程序。我安装了 MathGreek，显然弄乱了我所有的希腊语编码。我卸载了它，现在一切都运行正常了。唯一的问题是，在我使用的许多乳胶文件中，我认为卸载 MathGreek 导致文件中的每个希腊字符都被替换为相应的乳胶命令。例如 υ--> \upsilon..... 这应该是我未来的一个教训。谢谢大家！！
