Display ' apostrophe

Question

Is there a small package free way of implementing something like this in pdflatex and LaTeX?

I wish for the outcome of

\documentclass{article}
\begin{document}
    `It's a nice day!'
\end{document}

To be

ʻIt's a nice day!ʼ

I know that due to there being a single apostrophe inside the quote can mess up stuff, so I'm more then happy to use a function or macro, like \apos, to insert it.

I know that the apostrophe I want has the Unicode value of 39, so is in the standard ASCII implementation. "U+0027 ' apostrophe (HTML: ' ') typewriter apostrophe."

Answer 1

It's a rather unusual convention, but if you want it then:

\documentclass{article}
\usepackage{textcomp}
\begin{document}
    `It\textquotesingle s a nice day!'
\end{document}

Answer 2

David's answer is preferable, but here's another option if you don't want to load any package to take care of it.

\documentclass{article}
\begin{document}
`It\textsc{\char13}s a nice day!'
\end{document}
