[Darshan-users] dxt_analyzer.py: 'invalid continuation byte' error

[Carns, Philip H.]

Hi Sam,

I'm not sure off hand what would cause that.  Can you share the log file by any chance (you can send it to me directly if you would prefer not to post it on the mailing list)?  I can try to reproduce on some other systems and see if that narrows down the problem.

thanks,
-Phil

Subject: [Darshan-users] dxt_analyzer.py: 'invalid continuation byte' error

Hi all,

I have tried the following command both on Ubuntu 16.04 (python 3.5) and on SUSE Linux Enterprise Server 15 SP1 (python 3.6) and got the same error:
```
$ python3 /usr/local/bin/dxt_analyzer.py -i omlins_a.out_id1174947_10-9-40448-1694713884344482404_1602235659.darshan
Traceback (most recent call last):
  File "/usr/local/bin/dxt_analyzer.py", line 264, in <module>
    for line in infile:
  File "/usr/lib/python3.5/codecs.py", line 321, in decode
    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe6 in position 24: invalid continuation byte
```

With python 2.7.12 (on Ubuntu), I did not get the error, but the generated plot was empty.

Note that the input file does contain values generated by DXT:
```

```

Can you fix this / help me to get this working?

Thanks!!

Sam
