Microtypography protrusion with Polish quotation marks
Use T1
fontencoding instead of OT4
(default).
\documentclass{article}
\usepackage[T1]{polski}
\usepackage[utf8]{inputenc}
\usepackage{microtype}
\begin{document}
\noindent
``Lorem'' \newline
,,Lorem'' \newline
Lorem \newline
ć, ń, ó, ś, ź, ż, ą, ę, ł \newline
Ć, Ń, Ó, Ś, Ź, Ż, Ą, Ę, Ł
\end{document}
EDIT: This has been fixed in version 2.7b (28 Feb 2019).
The default microtype
configuration lacks protrusion settings for the „
ligature. You can add them like this (in the preamble):
\LoadMicrotypeFile{cmr}
\SetProtrusion
[ name = cmr-OT4,
load = cmr-OT1]
{ encoding = OT4,
family = cmr }
{
"FF = {500,300}
}
