Wow, sounds like techie ssids :-) My editor just displays ssids like
[ESC][BS][NAK][US][..]
After some research, both theoretical and practical one my router, I found out
that ssid names seems to be less standardized than expected. For example my
router allows non-ascii ssids.. So stripping out all non-ascii characters might
discard information :-(
If we're sure, that Android is comfortable with the ssids, we might solve the
problem instead by replacing the FileWriter in xml exporter with an UTF-8
compatible OutputStreamWriter.
So let's address the ssids:
1) Did you, by chance, notice the 'real' ssid while logging?
2) Could you verify what's stored in the radiobeacon database?
(via 'adb pull data/data/org.openbmap/databases/radiobeacon')

Maybe some people do that on purpose, as a DOS attack on piggybackers,
data-hungry Street View cars and the like :-)
Unfortunately I did not look at the real SSID as displayed by Android. I'll
check the XML where it was, maybe I get near that area and can check what gets
displayed.
I'll try to extract the relevant data from the local db and attach it.
As for stripping data, I meant something slightly different: Given that
openBmap does not store any plaintext SSIDs but only hashes (for privacy
reasons, as the SSID may often contain personal data, such as the owner's
name), do we actually need to upload the SSID in plaintext, or is it sufficient
to just send the hash? If the plain SSID is optional and the server will accept
XML files with just the hash, then that might be an option.

Attached a database with one of the SSIDs that produced a "krank" XML file.
Since the DB is some 150 MB in size, I pulled it from my phone and deleted all
networks other than the questionable one (identified by its MAC address) from
the wifis table. The wifi was observed in exactly one session; I deleted all
other sessions and all references to it from the other tables.

Has been closed a while ago in a pragmatic way: SSID is optional anyways, so in
case SSID contains non-ascii chars no SSID is stored at all..
