Machine tracker crashes when inputting non-ASCII characters in search

[Morten Brekkevold]

If one inputs an invalid search term in Machine Tracker's IP search, nothing seems to happen. If one inputs non-ASCII characters, however, the Machine Tracker crashes with a UnicodeEncodeError (NAV 3.13.0 and 3.13.1):
