Description Niko Lehto cendio 2020-11-19 14:15:21 CET 
On RHEL8 with system locale set to sv_SE.ISO 8859-15 (Latin-9).
If the username contains UTF-8 characters the profile selector will not set up environmental variables correctly. This is what I get in xinit.log with the username böngt:

Comment 1 Pierre Ossman cendio 2021-04-21 12:31:41 CEST 
We can't fix this as long as systemd/dbus refuses non-UTF-8:

> POSIX does not specify the encoding of non-ASCII environment variable names or
> values and allows them to contain any non-zero byte, but neither dbus-daemon
> nor  systemd supports environment variables with non-UTF-8 names or values.
> Accordingly, dbus-update-activation-environment assumes that any name or value
> that appears to be valid UTF-8 is intended to be UTF-8, and ignores other names
> or values with a warning.

We can probably improve the error message though.
Comment 2 Pierre Ossman cendio 2021-04-30 09:37:22 CEST 
Some improvements were made to the error message for bug 7691.
