I'm using impnattypo package with nosingleletter option under TeXLive 2016. With no luck.
I want to move last 'single letter' word to another line. Examples in one-letter word at the end of line also doesn't work.
Here's minimal example (take a look at the letter 'a' at the end of the first line).
\documentclass{article}
\usepackage[english]{babel}
\usepackage{blindtext}
\usepackage[nosingleletter]{impnattypo}
\begin{document}
\Blindtext
\end{document}
LuaTeXinternals changed quite a lot in the current version, it seems thatimpnattypopackage needs to be updated in order to support these changes – michal.h21 Jul 22 '16 at 18:11LuaTeXsupport inimpnattypopackage? https://github.com/raphink/impnattypo/issues/6 – Leonid Aug 16 '17 at 20:39
