** Description changed: Booting the live installer gave a UnicodeDecodeError when trying to read my Wi-Fi card as there are some malformed characters appended to its - name (not as it appears in Window's Disk Management) in the 2nd image in - the uploaded PDF. The "Friendly Name" as it appears in the Windows - Registry is "MediaTek Wi-Fi 6E MT7922 (RZ616) 160MHz PCIe Adapter", and - the description is "@oem22.inf,%rz616.devicedescexc%;MediaTek Wi-Fi 6E + name as it appears in Window's Disk Management (2nd image in the + uploaded PDF).

Those are both similar but different to the name that appears on the installer, but it has "USB WW WLAN<?>R<<?><?>N/A" appended, where "<?>" are non-ASCII characters that are unable to be displayed. The traceback shows `'utf-8' codec can't decode byte 0xec in position 80`, which means the bytes aren't invalid. This is likely a bug in the Wi-Fi adapter's firmware or EEPROM data, but - giving a fatal crash from reading malformed characters I would consider - as a bug in Subiquity as 1 adapter being unusable doesn't usually - prevent the installation. Just a warning that one of the network - adapters wasn't able to be read would be ideal.

The only workaround I found was to disable the adapter before the error appeared (this had to be done in < 5 seconds), trying to disable the adapter after the error by re-running the installer just gives the same error, and subsequent runs of the installer result in the loading icon just spinning forever with nothing else being shown. If the name I had to type was longer, I probably wouldn't have been able to remove the module before the error occurred, so this fix isn't reliable. Walking through the installer after fixing the network adapter issue, it also quit at random button presses the first 3 times, but eventually I was able to install Ubuntu. I'm not sure whether this is related to removing the module, but I'll include it in this bug report in case it is. This issue occurred with another USB, and I was able to install Debian on my laptop without any issues. I assume this bug can be reproduced by any Wi-Fi network adapter with non-ASCII characters presented. The fix for this could involve either just using UTF-16 as the encoding to be used for the network adapter names if that's possible to do when calling the Python libraries that end up calling `encode_unicode_string`, or by having a catch block to attempt to decode the adapter name using UTF-16.
