The unicode character for the square box □ is not defined, but
you can replace it by: \Box{}.  In addition this requires to use
the package "latexsym", and to be written in mathematical
context, so \(\Box\), or $\Box$ if you prefer sticking to the
style of the author.

Once this is done, pdflatex chokes on $\upsigma$ which looks to
originate from TeX StackExchange[1], so maybe the \Box{} thing
will be sufficient in the context of the original document.  But
if you also cannot render the \upsigma thing, then maybe try a
regular \sigma.  A working test document looks like:

	\documentclass[]{scrartcl}
	\usepackage[utf8]{inputenc}
	\usepackage{hyperref}
	\usepackage{latexsym}
	\begin{document}
	Bla \textbf{TIR (\(\Box\)x$\sigma$/Exp.) 3D}
	\end{document}

Once rendered, your test document looks like:
	    _____ _ _________
	Bla TIR (□xσ/Exp.) 3D

with the overline figuring a bold face.  I don't know for sure
this is the expected result, but fair enough.  I suspect the
initial intent was to get the whole "TIR.*3D" into nice bold
font.

Hope this helps,
