This is a feature of LaTeX fonts: the ASCII quote and backtick are mapped
to "typographical" quotes u2019 and u2018: ab’c de‘f

Here, I get the "typographical" quotes u2019 and u2018 in a teletype
font: ab’c de‘f
With Document>Settings>Fonts>non-TeX fonts, the PDF output is as expected:
ab'c de`f

In case using Unicode fonts is not an option, you may also try the
"listings" package (Insert>Program listing) with the options
upquote=true
basicstyle=\ttfamily
in Document>Settings>Program listings. In a minimal document, you may
need to add \usepackage{textcomp} to the LaTeX preamble.
A a last ressort, you can use the macro \textasciigrave (instead of
\char18) in raw LaTeX (ERT).
