Yes! ;-) You compiled with pdflatex, right? I discovered that it works
for me with pdflatex but *not* with lualatex???

If you compare the following 2 URLs (1: pdflatex, 2:lualatex)

http://maps.googleapis.com/maps/api/staticmap?center=Bergheimer%20Stra%c3%9fe%20110A%2c%2069115%20Heidelberg%2c%20Germany&size=600x400&zoom=17&markers=size:mid|color:blue|label:1|Bergheimer%20Stra%c3%9fe%20110A%2c%2069115%20Heidelberg%2c%20Germany&maptype=roadmap&scale=1&format=png&language=en&sensor=false

http://maps.googleapis.com/maps/api/staticmap?center=Bergheimer%20Stra%c3%3fe%20110A%2c%2069115%20Heidelberg%2c%20Germany&size=600x400&zoom=17&markers=size:mid|color:blue|label:1|Bergheimer%20Stra%c3%3fe%20110A%2c%2069115%20Heidelberg%2c%20Germany&maptype=roadmap&scale=1&format=png&language=en&sensor=false

pdflatex encodes 'ß' to %c3%9f, which is the correct utf-8 encoding for
ß, but lualatex encodes it to %c3%3f. Strangely, luatex works for the
other adresses with umlauts.

Any idea why luatex behaves different??
