I am working on the fix for this now. However, to ensure we fully
understand the problem, please could those seeing this problem attach
file /var/log/udev to this bug so I can see the raw data.
By the way, if you simply 'cat' the file(s), you won't necessarily see
the extended characters since as they are generally not printable, the
terminal driver won't display them. However, you can detect them by
doing something like:
grep "[^[:print:]]" /var/log/udev /proc/acpi/battery/BAT0/info
Or if you want to see them:
grep "[^[:print:]]" /var/log/udev /proc/acpi/battery/BAT0/info | od
-xc
Vim also highlights extended chars by default.
