It's not even unprintable characters -- just punctuation.

I'm not 100% sure this is the problem, but it seems highly likely given that
the two places it reliably crashes are the two places iwlist scan shows
url-formatted ssids.

And yes, it's certainly a bug -- data literally *floating out there in the
air* should not crash any program.
