The above error messages are seen when connecting to a JLink with a specified serial # 60126753, see below.
" self.detailed_log_handler = lambda s: (detailed_log or logger.debug)(s.decode())
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd0 in position 25: invalid continuation byte

I see the same error on rasperry pi 4 model B with: Linux raspberrypi 5.10.17-v7l+ #1421 SMP Thu May 27 14:00:13 BST 2021 armv7l GNU/Linux
I connected the jlink to a NRF52 chip.
I tried with JLink_Linux_V672d_arm.tgz and the error is not present but as soon as I try to use the version 7 (I tried with JLink_Linux_V700a_arm.deb and JLink_Linux_V750_arm.deb) the problem appears.
Tried with JLink_Linux_V698e_arm.deb and the error is present so it is not related to the version 7
Environment :
Ubuntu 18.04.5 LTS (on a HP Prodesk https://support.hp.com/us-en/document/c05364047) CPU: Intel Core i5-7500T@2.70 GHz x4 (4-Core) - systems that show the problem.
Memory: 8 GB Disk : 250 GB OS: 64-bit, Ubuntu 18.04.5 LTS Release: 18.04 Codename: bionic
JLink hardware used: JLink base, https://shop-us.segger.com/J_Link_p/8.08.00.htm with FW version 6.80
Expected vs actual behavior:
Existing python code that works well with pylink-square 0.9.0 gives UnicodeDecodeErrors with pylink-square 0.10.10 and the above JLink configuration. Error messages are shown below. It appears it only happens on certain Ubuntu 18.04.5 LTS systems (have 3 always repro'd hosts but not 10 others). It might be that pylink-square is dependent on some other python packages in the system to show this error, otherwise it would show up everywhere. For what it's worth, the other 10+ Ubuntu systems have more powerful config, but I don't think that's the issue since the SW is the same.
CPU: Intel Core i5-9500T@2.20 GHz x6 (6-Core) - systems that don't show the problem (pylink-square 0.10.0 works fine) Memory: 16 GB Disk : 483 GB OS: 64-bit, Ubuntu 18.04.5 LTS
