Well regarding the apostroph and ' there is no problem in lualatex:
The mapping is already done with (faked) ligatures:

\documentclass[]{scrartcl}
\usepackage{fontspec}
\begin{document}

a'b a^^^^2019b

\setmainfont{Arial}
a'b a^^^^2019b

\setmainfont[Ligatures=TeX]{Arial}
a'b a^^^^2019b

\verb+a'b+ 

\end{document} 

(You get ' in the verb as the typewriter font doesn't activate the
tex-ligatures).

You can implement more substituations with feature files.
