[tex4ht] [bug #620] tex4ht breaks URL text leading to empty spaces between words generated in final HTML when \urldef

[Michal Hoftich]

Follow-up Comment #1, bug #620 (project tex4ht):

The original issue is caused by your URL not fitting on a line, so it gets a
linebreak, resulting in white space. The solution is to use larger
\textwidth.

We also found an actual bug, that using the `]` character in \href produced a
wrong link. I hopefully fixed that in the sources.

https://tex.stackexchange.com/questions/707149/tex4ht-breaks-url-text-leading-to-empty-spaces-between-words-generated-in-final

I use \urldef in order to make href, because the names are folder/file path
which can contain many different strange characters.

This works fine in PDF with lualatex. But I noticed that the HTML generated by
tex4ht breaks the names into 2 lines, which causes BLANK space to show in the
name when looking at it on the screen in the page. This makes it hard to read
sometimes. Here is MWE


\documentclass[12pt,oneside]{book}
\usepackage{hyperref} 
\usepackage{url}

\begin{document}

\section{Tests completed}
\begin{enumerate}
\item
\urldef\mytarget\nolinkurl{test_cases/rubi_tests/0_Independent_test_suites/1_Apostol_Problems}
\href{test_cases/rubi_tests/0_Independent_test_suites/1_Apostol_Problems/output/report.htm}{\mytarget}
\hspace{5pt}  [175]
\item
\urldef\mytarget\nolinkurl{test_cases/rubi_tests/0_Independent_test_suites/2_Bondarenko_Problems}
\href{test_cases/rubi_tests/0_Independent_test_suites/2_Bondarenko_Problems/output/report.htm}{\mytarget}
\hspace{5pt}  [35]
\end{enumerate}
\end{document}

When compiled using

make4ht -ulm default -a debug  index.tex "mathjax,htm,nostyle"

It gives

enter image description here

The reason this happens is because tex4ht breaks the name when it sees _. Here
is the raw html

window.MathJax = { tex: { tags: "ams", }, };

Apostol_Problems  [175]

 test_cases/rubi_tests/0_Independent_test_suites/2_
Bondarenko_Problems  [35]
 
 



If I edit the index.htm by hand and make the name one long line by removing
the extra CR it added, the HTML now becomes

and on screen it now looks like this

How to fix tex4ht so it does not break long names in href and keep the name on
same line?
