I found a partial solution:

    for file in files: print(file.encode('utf8'),file=flo)

But this works only for files I get from Tk askopenfilename(), not for
files from sys.argv[]
Then I see:

S:\>python fexit.py -a x.zip C:\Users\admin\_XöX.exe .
files selected:

"C:\Users\admin\_X÷X.exe"
2015-12-07 16:17:15
114 kB

Traceback (most recent call last):
  File "fexit.py", line 2166, in <module>
    wexit(main())
  File "fexit.py", line 260, in main
    status = sendfile_retry(files,recipient,comment)
  File "fexit.py", line 959, in sendfile_retry
    for file in files: print(file.encode('utf8'),file=flo)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xf6 in position 17:
 ordinal not in range(128)
