I got text justifying problem when I change the default font to a monospaced font, as you can see in my MWE.
Note that this does not only happen in article class, but also in memoir, book, as well.
\documentclass[12pt]{article}
\usepackage{lipsum}
\usepackage{tgcursor}
\renewcommand*\familydefault{\ttdefault}
\begin{document}
\lipsum
\end{document}
How can I fix it? Please help me.
Thanks
