I'm not sure what you mean here with requiring encoding and why this
change would be needed.

All this text would go into the commit message and as such, this type of
notes should not be included.

It does in my tests..
./wpa_passphrase "netwörk" thepassword > /tmp/a.conf
./wpa_supplicant -i wlan0 -c /tmp/a.conf -dd
...

That hexdump of the SSID matches the one shows up above without any
wpa_passphrase modification..

UTF-8 encoded 'ö' ended up getting encoded as c3b6 in the ssid parameter
and wpa_supplicant reads that as-is.

There should not be space between "Signed-off-by" and ":".

bool is the currently preferred type for boolean values in new code even
thought int is still uses in hostap.git for most cases.
