I add \href in \subsection{}, this make the url become all capital, how can I deal with this?

For example, I use \subsection{\href{http://finance.sina.com.cn/roll/2018-06-30/doc-iheqpwqz3115534.shtml}{some text}} and run latex, it shows like this. enter image description here And It contains an url.

Then when I click the link, the url becomes http://finance.sina.com.cn/ROLL/2018-06-30/DOC-IHEQPWQZ3115534.SHTML like this: enter image description here in the web-browser. All the letters become capital, this url cannot open the right website.

What can I do to fix this? I want the url can open the right website. Thank you.

    Copying the example in your post body, I do not replicate the behaviour you describe. Please could you produce a Minimum Working Example which reproduces the problem? Jul 6, 2018 at 7:36

    An example that could reproduce this is \documentclass[british]{article} \usepackage[T1]{fontenc} \usepackage[utf8]{inputenc} \usepackage{babel} \usepackage{hyperref} \begin{document} \MakeUppercase{\href{http://example.com/lowercase}{some text}} \uppercase{\href{http://example.com/lowercase}{some text}} \end{document}

    Maybe tex.stackexchange.com/q/274734/35864 can help

  • The work-around in the linked question seems to work here is well, \documentclass[british]{article} \usepackage[T1]{fontenc} \usepackage[utf8]{inputenc} \usepackage{babel} \usepackage{hyperref} \protected\def\mylink{http://example.com/lowercase} \begin{document} \MakeUppercase{\href{\mylink}{some text}} \uppercase{\href{\mylink}{some text}} \end{document} but maybe there is something cleverer.

  • Sir, but if you use \href in \subsection{} like \subseciont{\href{}{}}, all the letters will become upper case.

Something like this will work! :- \subsection{\texorpdfstring{\lowercase{\href{http://finance.sina.com.cn/roll/2018-06-30/doc-iheqpwqz3115534.shtml}{\MakeUppercase{some text}}}}{}}

Since by default, the whole text in a subsection is in upper-case, hence after wrapping \lowercase over whole \href part, this upper-case has to be done forcefully (here using \MakeUppercase).

Also, \texorpdfstring has been used to avoid the warning:
Hyperref warning - Token not allowed in a PDF string

(There may be other work-arounds too)


There is an answer to a similar question here: Hyperref capitalizes the URL
which worked for me!

Check this example out:

\usepackage[left=1.50cm, right=1.50cm, top=1.50cm, bottom=1.50cm]{geometry}
\newcommand{\runsubsection}[1]{\uppercase {#1} \normalfont}


    Here is an example:\\
    Hover your mouse over the urls to see what url they are representing:\\
    there are the same urls inside the same command($\backslash$runsubsection), but the $\backslash$uppercase command converts the first url to UPPERCASE.\\[10pt]
    \runsubsection{\href{https://drive.google.com/file/d/someUPPERandLowercaseURL123456/view}{some Normal Text for url}}\\
    \runsubsection{\Myurl{some Normal Text for url}}

    Could you add some code here showing what you're talking about? The question you link to was closed because it looks like OP was putting \href in a \section, but didn't actually do so in their code, so the answer doesn't really reflect what's happening in this question.

Tried many ways for hours and got myself caught into a simple solution instead of including a link into subsection. Do the opposite.

Before : \subsection{\href{sometext.com}{some text}}

Wasn't working because some inbuilt function capitalized the link.

After : \href{sometext.com}{\subsection{some text}}

This finally worked for me 😊
