Cabin font doesn't render properly apostrophe

Question

I'm using Cabin font with XeLaTeX. The apostrophe is not render properly.

As you can see on the following screenshot, there is not enough space betweend L and a.

On this screenshot (with the default LaTeX font), there is no problem:

Is it possible to fix this?

MWE (use XeLaTeX):

\documentclass[12pt]{article}
\usepackage{fontspec}
\setmainfont{Cabin}
\begin{document}
L'apostrophe
\end{document}

Answer 1

It seems that it is very tightly spaced to following lowercase letters (1). You can prevent the kerning with \mbox (2). I assume a word space is too much (3) or you could use the xetex inter-character token class to add an extra kern, here I set up a class for ' and a class for lower case ascii letters and inject a small kern if ' is followed immediately by a letter.

\documentclass[12pt]{article}
\usepackage{fontspec}
\setmainfont{Cabin}

\begin{document}
L'apostrophe

L\mbox{'}apostrophe

L' apostrophe

\XeTeXinterchartokenstate=1
\newXeTeXintercharclass\aposclass
\newXeTeXintercharclass\letterclass
\XeTeXcharclass`\'=\aposclass
\count0=`a
\loop
\XeTeXcharclass\count0=\letterclass
\advance\count0 1
\ifnum\count0<`z
\repeat
\count0=1

\XeTeXinterchartoks\aposclass\letterclass{\kern.1em}

L'apostrophe

\end{document}
