Unfortunately, I have to report that your diff does not change anything
on my side.

$ kpsewhich getmap.sty
c:/texlive/2018/texmf-dist/tex/latex/getmap/getmap.sty

I expanded your test file with my troublesome address:

%
% UTF-8 encoding
%
\documentclass{article}
\usepackage{graphicx}
\usepackage[overwrite=true]{getmap}
\begin{document}
\getmap[file=tokyo, mode=gm]{渋谷, 東京}
\includegraphics[width=10cm]{tokyo}

\getmap[mode=gm]{Bergheimer Straße 110A, 69115 Heidelberg, Germany}
%\getmap[mode=gm]{Bergheimer Strasse 110a, 69115 Heidelberg, Germany}
\includegraphics[width=10cm]{getmap}
\end{document}

Both work fine here with pdflatex and xelatex but not with lualatex!

Looking at the URLs you can see that also in your Tokio example there is
a faulty 3f byte, which seems to indicate some kind of systematic error
in luatex v1.0.7. At least my example worked with the version included
in TL2016 (for sure) and most likely TL2017!

@Ulrike: Can you please test the above test file both with lualatex
v1.0.7 and v1.0.8? Have you done your last test with the original
getmapdl.lua or with the adapted version?

Best,

Josef
