I think there is really a problem. While adding support for Google Maps 
for my getmap package 
(https://bitbucket.org/kleberj/getmap/raw/ee40738fc90e492745f2228cac8fbd397a592653/dev/scripts/getmap/gmimage.lua), 
i encountered problems with non-UTF-8 command line options:

texlua gmimage.lua -M "&markers=color:green|label:D|Pergamon 
Museum,Berlin&markers=color:blue|label:S|Bode Museum,Berlin" -C 
"James-Simon-Park,Berlin" -P "&path=weight:7|color:purple|Bode 
Museum,Berlin|Pergamon Museum,Berlin|Neues 
Museum,Berlin|James-Simon-Park,Berlin|Henriette-Herz-Platz,Berlin&path=weight:7|color:brown|Simon-James-Park,Berlin|Weinmeisterstraße,Berlin" 
-V "Brandenburger Tor,Berlin"

fails (only the last path is absent) because of ß in Weinsteinstraße, 
whereas

texlua gmimage.lua -M "&markers=color:green|label:D|Pergamon 
Museum,Berlin&markers=color:blue|label:S|Bode Museum,Berlin" -C 
"James-Simon-Park,Berlin" -P "&path=weight:7|color:purple|Bode 
Museum,Berlin|Pergamon Museum,Berlin|Neues 
Museum,Berlin|James-Simon-Park,Berlin|Henriette-Herz-Platz,Berlin&path=weight:7|color:brown|Simon-James-Park,Berlin|Weinmeisterstrasse,Berlin" 
-V "Brandenburger Tor,Berlin"

works (only ASCII). I tracked the problem down to a different encoding 
of ß to Weinmeisterstra%dfe (lua) or Weinmeisterstra%C3%9Fe (bash 
version + wget).

Strangely, that even does not work when calling texlua from bash 
(Cygwin), which uses UTF-8.

Running texlua (Windows) with an utf-8-encoded script does not seem to 
be a problem, but handing over command line options is! I wonder if the 
first texlua call does work on Linux and/or MiKTeX. Can somebody test?
