I downloaded the node from the api using osmosis and wrote it to an osm
I imported that osm file into an empty db schema.
I dumped the complete db schema (with the tiny data set) using osmosis
to a new osm file.
I loaded the file using JOSM and compared it to data retrieved direct
from the api.
The name value on node 78270 was identical for both.
The name value is now "Kronprinsesse Märthas allé" which looks correct
So the good news is that I'm almost positive osmosis doing the "right
thing". The differences between planet.rb and osmosis when dumping my
local db were hopefully just due to different handling of dodgy data in
my db. The both appear to do the right thing with correct data.
