Unicode decode error in aiohttp/client_reqrep.py

Configuration
1

I am running HA v0.97.1 on a Raspberry Pi (Hassbian). Everything is working very well so far … many automations, customizations and zwave devices all set up. I decided to take a look at the home_assistant.log file and discovered the following whenever I re/start HA. Did I mess up the UTF support during my install? I would like to fix this, so if anyone has any ideas, please let me know!

I never got a reply, but I still tried to investigate this. According to the following page:
https://stackoverflow.com/questions/19699367/unicodedecodeerror-utf-8-codec-cant-decode-byte
using ‘ISO-8859-1’ decoding works much more reliably.

If I add the last line below:

 if encoding is None:
     encoding = self.get_encoding()
 
 encoding = 'ISO-8859-1'

in
/srv/homeassistant/lib/python3.7/site-packages/aiohttp/client_reqrep.py
(in the async def text method) just before calling self.body.decode, everything now works.

I believe the un-decodable data was coming from a Samsung TV after hass discovered it.
