I'm converting a document written for print distribution to one for electronic distribution by turning all of the URLs into hyperlinked URLs. Using the hyperref package and \url command. A single URL is giving me the following error:

! TeX capacity exceeded, sorry [input stack size=5000].
\font@name -> \OT1/cmr/m/n/10.95
l.4 .../$FILE/Open%20Meetings%20Law%20FAQ.pdf}

! ==> Fatal error occurred, no output PDF file produced!
Transcript written on FSGuide2022ElecProbMinEx.log.

I can't figure out why.

Here's a minimal example (with the offending URL) that gives this behavior.


I'm probably making some silly mistake, but I can't for the life of me see what it is!

    hyperref doesn't like the \$, use only $. Commented Aug 24, 2022 at 19:31

    \usepackage[T1]{fontenc} works too. Commented Aug 24, 2022 at 19:41

There's something fundamentally wrong with the URL string shown in your posting. Specifically, why are the $ and %20 particles escaped with backslash characters?

In my view, both of the following versions of the URL string are correct -- observe that neither makes use of \ characters to "escape" TeX-special characters such as $ and %.

Sure enough, the test program

\usepackage[colorlinks,allcolors=blue]{hyperref} % optional
\url{https://app.lla.state.la.us/llala.nsf/BAADB2991272084786257AB8006EE827/$FILE/Open Meetings Law FAQ.pdf}


yields the following screenshot:

Happily, clicking on both hyperlinks sends you to the correct file.
