Yep. But at least the system fonts are considered at all.

That leads to a question that will arise when the system font fallback is
implemented: In what order should the system font fallback mappings be
defined? If you simply iterate over them as done here, the result can also
change (perhaps unexpectedly) if the user (un)installs fonts.

I supposed you'd have probe windows behavior by running tests while installing
and uninstalling system fonts.
