font-encodingshyperrefurls
When escaping the dollar sign inside a \url{} command, as shown in my MWE, the following is displayed. (Below is what I am expecting).
\documentclass[a4paper]{article}
\usepackage[T1]{fontenc}
\usepackage{hyperref}
\begin{document}
\url{test \$ test}
test \$ test
\end{document}
I do not have an idea what is causing this. I am using writeLaTeX to compile this – could that be the culprit?
Could this answer be the answer? How would I go about implementing that solution for a dollar sign?
Your error is produced by the following MWE:
\documentclass{article}
\usepackage{hyperref}
\begin{document}
Test\footnote{Footnote text.}.
\begin{table}[t]
\centering
\begin{tabular}{cc}
First & Second\footnote{Second footnote.}
\end{tabular}
\caption{Caption}
\label{tab:t}
\end{table}
\end{document}
this time with reference to {HFootnote.2}. The .2 means that is the second footnote causing the problem. Cutting and pasting your other code in does not produce the error your report from the table with a \parnote. So try to track down direct uses of the \footnote command in your document.
hyperref has all sorts of issues with footnotes. See the answers to the question Clickable Table Footnote, for discussion, why not to do this, and workarounds.
It's better to use a different command, so that its usage is clear:
\documentclass{article}
\usepackage{xcolor}
\usepackage[
colorlinks,
linkcolor=magenta
]{hyperref}
\newcommand\rurl[1]{%
\href{http://#1}{\nolinkurl{#1}}%
}
\begin{document}
This is a link \rurl{ipython.org} written in abbreviated form.
\end{document}
Of course you lose the tricks \url and \href are able to do with complex URI, for handling special characters, but short URI like this one should not have this problem.
The color in the image shows that it's indeed a link to a Web page.

There is no need to escape a dollar symbol in a url.
