LaTeX | hyperref error | Argument of � has an extra }. \end{document}

Issue

I got a new PC with Windows 10 Pro operating system several days ago and decided to install TeXstudio + MiKTeX.

And I faced a problem compiling LaTeX file. The problem is when I try to add \usepackage{hyperref} or code stuff similar to this line (more detailed in the code with the comment line % problem is here if I add this line) I get an error which says: Argument of � has an extra }. \end{document}.

My code:

\documentclass[10pt,a4paper]{report}
\usepackage{cmap}
\usepackage{setspace}
\onehalfspacing
\usepackage{multicol}
\usepackage{textcomp}
\usepackage{verbatim}
\usepackage{floatrow,calc}
\DeclareFloatSeparators{mysep}{\hspace{3cm}}
\thisfloatsetup{floatrowsep=mysep}
\usepackage{ucs}
\usepackage[pdftex]{graphicx}
\usepackage{epstopdf}
\usepackage{amssymb,amsmath}
\DeclareGraphicsExtensions{.pdf, .png, .jpg}
\usepackage[labelsep=period]{caption}
\usepackage[utf8x]{inputenc}
\usepackage[T2A]{fontenc}
\usepackage[russian, english]{babel}
\usepackage[left=3cm, right=1.5cm, top=1.5cm, bottom=2cm]{geometry}
\usepackage{indentfirst}
\usepackage{color}
\definecolor{Black}{rgb}{0,0,0}

\usepackage[unicode, colorlinks, linkcolor=Black]{hyperref} % problem is here if I add this line
\usepackage{xcolor}
\definecolor{linkcolor}{HTML}{000000}
\definecolor{urlcolor}{HTML}{000000}
\hypersetup{pdfstartview=FitH, linkcolor=linkcolor, urlcolor=urlcolor, colorlinks=True} % problem is here if I add this line
\fontfamily{ptm}
\parindent=1cm
\sloppy
\bibliographystyle{unsrt}
\usepackage{hyperref} % problem is here if I add this line

\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhf{}
\lhead{\leftmark}
\cfoot{\thepage}
\renewcommand{\headrulewidth}{1pt}

\usepackage{subfig}

\usepackage{epigraph} %%% to make inspirational quotes.

\usepackage{amsfonts}

\begin{document}

Random text
    
${\mathcal {E}}=-{{d\Phi_{B}} \over dt},$ where

${\mathcal {E}}$ — random letter.   

\end{document}

Error I get:
Error

When I try this code in OverLeaf or on my notebook or without hyperref packageseverything’s fine. But I need this package if, for example, I’ll have to add references…

Did someone face similar problem? Maybe I need to install some other packages?

Solution

A quote from the hyperref documentation:

Note: utf8 is now the default in LATEX and ucs is no longer recommended.

If ucs and utf8x is removed, your code compiles.


  • Furthermore you should remove the pdftex from graphicx. It will automatically choose the best suited option to match your compilation chain.

  • You should also not load the same package multiple times, in particular not with different options

  • And load hyperref after the other packages (there are only very view exceptions)

  • No need to load color if you also load xcolor
