csquotes: wrong kerning?

Question

I found that with enquote in the csquotes package, the closing double quote is too close to the last letter:

\documentclass{article}
\usepackage{csquotes}
\begin{document}
\noindent
\enquote{nature of}\\
``nature of''
\end{document}

Is this a known bug (which I don't have to report)? I use pdflatex in texlive 2016.

Thanks! If csquotes doesn't work correctly without fontenc, it should issue at least a warning, I suppose. Should I ask the creator of the package to consider it as an enhancement? (I prefer enquote to manual quotes because it handles nested quotes automatically.) — Ryo, Jun 19 '17 at 07:07

It is not csquotes fault, it is a problem in the OT1-fonts: The kerning is missing if the quote symbol is entered directly and not through a ligature:

\documentclass{article}

\begin{document}

of''
of\char"22
of\textquotedblright


\fontencoding{T1}\selectfont
of''
of\char"11
of\textquotedblright
\end{document}

So this is another reason not to use OT1-encoding -- at least if you want to use the computer modern fonts (the lmodern fonts e.g. don't have this problem).

Thanks for your comments! Your and egreg's answers indicate that ot1enc.def has to be fixed. My next question then is why it's not done and why T1 is not default---If, on the other hand, there are valid reasons for OT1 to remain unfixed and default, then there should be warnings when some packages are broken under OT1. It's like internal feud :-) The csquotes camp blames OT1 and the OT1 camp blames csquotes and the uniformed (me) is confused :-) – Ryo Jun 19 '17 at 12:39

You can fix what ot1enc.def does (which is, in my opinion, wrong):

\documentclass{article}
\usepackage{csquotes}

% ot1enc.def has
%\DeclareTextSymbol{\textquotedblright}{OT1}{`\"}
% fix it
\DeclareTextCommand{\textquotedblright}{OT1}{''}

\begin{document}

\noindent
\enquote{nature of}\\
``nature of''
\end{document}

Just load fontenc with the T1 option (before inputenc in case you use it [compare]).

\documentclass{article}
\usepackage[T1]{fontenc}
%\usepackage[utf8]{inputenc}
\usepackage{csquotes}
\begin{document}
  \noindent
  \enquote{nature of}\\
  ``nature of''
\end{document}
