The value Data Units Read is not present on the smartctl provided...

¡Second interesting issue of the day!

Please, provide the output as the last time: sudo smartctl --all /dev/nvme0n1

there should be something weird with your setup.

I suppose it should be related with lang/location, but not sure why.

The character   that is returned by your smartctl should be just a comma ,.

I'm going to consider this as a corner case and support it... but I would appreciate if you can share the env variables or other conditions that may lead to this anomalous behaviour .

Thank you in advance

[ralequi]

Try the develop release (you can install using pip install git+https://github.com/truenas/py-SMART@develop) and tell me if it is fixed or not.

Add here any other utf8/encoding issues you found out there.

Thank you for your time.

@ralequi The develop release works! no other issues found

[ralequi]

I'm closing this issue then.

I would double-check this as it seems there is something strange on windows with this character. I'll try to fix it before merge the fix into master.

Thanks again!
