Zenmap crashes when file not found with error like: "UnicodeEncodeError: 'utf-8' codec can't encode characters in position 897-900: surrogates not allowed"

[fyodor]

We've received many reports (often with tracebacks but very little other context) of Zenmap crashes with a UnicodeEncodeError when a file isn't found. They started with Nmap 7.94, which means it is likely that it relates to the Python3 Zenmap upgrade which considerably changed Unicode handling. Here are some Tracebacks that were sent to the public Nmap development list that might help us track this down:
