Hello,

I have noticed that abstractions/user-download profile allows to download into 
home directory, while protecting dot files:

owner @{HOME}/[a-zA-Z0-9]*           rwl,

Though it fails for files with non-latin symbols, tested with /usr/bin/tee copied to /usr/local/bin/testtee with minimal profile using user-download abstraction:

echo "foo" | testtee ~/ąčęėįšųūž
testtee: /home/vincas/ąčęėįšųūž: Permission denied

When file rule is changed into:

owner @{HOME}/[^.]*                  rwl,

It works as expected:

$ echo "foo" | testtee ~/ąčęėįšųūž
foo

$ echo "foo" | testtee ~/.bashrc
testtee: /home/vincas/.bashrc: Permission denied
