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"

Traceback (most recent call last):

 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:
